Aranet Case Study – Wireless monitoring sensors in Getliņi greenhouse

Wireless Monitoring Sensors

Aranet Case Study – Wireless monitoring sensors in Getliņi greenhouse

You can use the gas from a waste landfill to produce electricity, then use the excess heat to warm greenhouses. This is the genius thinking that empowers SIA Getliņi Eko. And this is also why they run one of the most advanced greenhouses in the Baltic region. Genius thinking and genius people behind it.

Getliņi manages the largest municipal solid waste landfill in the Baltic States. Recycling waste produces biogas. They burn biogas to produce electricity. Then they sell this electricity to the grid. This process produces a lot of heat. This heat is used to keep the greenhouses warm. Together more than a hectare of tomatoes, cucumbers and potted flowers. Now this is a smart optimization of resources.

They were the first greenhouse in the world that implemented LED lighting for cucumber growing. And they continue to lead the way in technological development.

You can’t optimize if you don’t measure. This is where Aranet comes in.

“We are fighting for every half of a degree,” says the chief agronomist Guntars Strauts, “energy efficiency is our utmost concern”. It is not enough to measure the temperature only in the center of the greenhouse with a climate box. This does not give you all the information you need to optimize costs.

You need to know what is going on everywhere, even in remote corners. Is one side colder? Did someone forget to close the window? You would never know if you were measuring only in the center.

The Aranet system offers flexibility by using wireless sensors for all measurements. Put the sensors anywhere you want. Change the location as often as you need. No wires, no hassle. Cost efficient. Simple.

Getliņi took it a step further. They now use the Aranet system to measure on 3 levels of the plant – top, middle and bottom. Maybe the lower level is fine, but the tops of the tomato plants are overheating. Time to close the shades.

Plant weight is an important matter. It’s very satisfying that it can be measured in the same Aranet system. All in one dashboard. You know how much water is coming in. You weigh the plants. You weigh the drainage. You get your biomass increase. You can be even more precise if you want. Aranet temperature sensors also measure relative humidity. You can use this to get the use vapor pressure deficit. Then calculate the evaporation and subtract it.

The flexibility offered by wireless sensors is immense. It takes time to comprehend all the applications. It takes time to escape the “wired” thinking. Time to break loose from the limitations of wires.

Aranet Case Study – Wireless temperature monitoring in Latvia’s largest supermarket chain, Rimi Baltic

Wireless Monitoring Sensors

Aranet Case Study – Wireless temperature monitoring in Latvia’s largest supermarket chain, Rimi Baltic

If a refrigeration unit in your supermarket breaks down you don’t have to worry about spoiled products. Provided that you have the Aranet smart sensor system installed, as Rimi Baltic has… Rimi Baltic is a major retail operator in the Baltic states based in Riga, Latvia. It is a subsidiary of the Swedish group ICA. Rimi Baltic operates 83 retail stores in Estonia, 56 in Lithuania and 125 stores in Latvia. They also operate supply-chain distribution centers in each of these countries.

When Aranet representatives first started to investigate supermarkets, it was a surprise for us how often data collection still depended on manual pen and paper recording. Measurements such as freezer temperatures were susceptible to human error and problems could only be detected after the fact.

In the summer of 2018 Rimi Latvia gave Aranet a chance to prove the quality of our wireless sensors for refrigeration unit temperature monitoring.

The superior quality of the Aranet system became apparent – where our competitors needed 3 base stations to cover a large supermarket, Aranet did it with only one. Because of the advanced performance of our technologies Aranet proved itself to be the best solution for Rimi’s needs.

Today 7 000 Aranet wireless sensors are installed in all 125 Rimi supermarkets in Latvia.

If something goes wrong with a refrigeration unit the Aranet system immediately alerts the food safety manager that temperatures are experiencing a variance outside of optimal range so that corrective actions can be taken.

Currently all of the Rimi stores in Latvia access the Aranet Cloud for centralized monitoring and data analytics. No more manual temperature data logging means greatly reducing losses associated with non-saleable products. Automated temperature monitoring and minute-by-minute notifications of variances greatly simplify compliance with the HACCP process.

Even in the largest Rimi supermarket, 8 800 m2 – about the size of a city block, the wireless signal of a single Aranet base station can cover the whole store.

After implementing the Aranet sensor system additional benefits are becoming apparent. Rimi Baltic outsources the operation and maintenance of refrigeration units. With the data provided by Aranet, stores can save on the energy costs of operating the refrigeration equipment by keeping the units running at the optimal temperature range. In accordance with food safety guidelines Rimi must maintain their frozen food inventory at -20°C. By using the Aranet system Rimi learned that the outsourced maintenance company was keeping some of the freezers at temperatures as low as -30°C. The ambient temperature at Rimi supermarkets is usually kept around 20°C. This means that the temperature difference between the freezer and the store temperature was 32°C, when it should have been 22°C. Aranet data analytics identified substantial savings of 20% by reducing energy costs associated with operating these units.

The Aranet system is a plug-and-play solution that allows a supermarket to protect itself from unnecessary food spoilage and potential food safety violations. As an added benefit it allows for an easy record keeping for reporting and traceability.

You can only improve what you measure. Time to choose Aranet!

Smart devices or central portal – HW group follows both trends in IoT sensor technology

HW group - Monitor and Remote Control

Smart devices or central portal – HW group follows both trends in IoT sensor technology

HW group devices follow the two current trends in sensor technology. First, there are simple single-purpose devices with IoT network topology, dependent on a central cloud application for control. Then, there are smart devices for autonomous operation and networks with high security requirements. Each solution has its own advantages. Simple devices offer simple installation, configuration and central maintenance, thus reducing maintenance costs during the entire lifetime.

Advantages and disadvantages of simple vs. smart devices

The question whether it is better to use single-purpose devices or rather to integrate more functions into one device has been debated since the first microprocessors. By using more single-purpose devices, better system scalability can be achieved but possibly at higher costs. By integrating functions, hardware costs can be significantly reduced but there is an increased risk that a fault in one subsystem will make the whole system inoperable.

At the same time, the decision whether to use smart autonomous devices or a cloud-based solution should not be based on the device costs alone; it must reflect the actual application – for what purpose is an independent monitoring solution being implemented – as well as the system design and installation.

Smart devices like HWg Damocles2, Poseidon2, Ares LTE…

System design and scalability

Simple single-purpose devices offer a clear advantage. They contain a small, clearly-defined number of inputs, outputs and sensors. They do not combine functions within a single package; however, it is easy to combine different devices. This makes it much easier to design the entire ecosystem and also to extend it.

When designing a monitoring solution, it is important to keep in mind not just the function but also the range of monitored elements and quantities. Monitoring can encompass elementary quantities, such as temperature and humidity, and also things such as door contacts, equipment states, voltages or currents. From this point of view, single-purpose devices and smart devices serve equally well. In simpler applications, smart devices have an advantage because an all-in-one solution provides all the necessary elements and functions at low installation costs. So, to monitor the environment inside a rack, all that is needed is a STE2 with a thermometer, a humidity sensor and two door contacts, or a Poseidon2 3268 that can also control additional fans. However, in case of more complex applications, it is harder to keep the costs under control. Smart devices provide a limited number of inputs, outputs and sensors in various combinations; therefore, it is necessary to know all the available models and choose a suitable combination. It can easily happen that a user who needs just 1 additional digital input ends up purchasing an entire additional (and expensive) device.

Installation and configuration

Simple single-purpose devices are all configured at a single place – the central SensDesk portal.

Simple devices themselves do not process data in any way; they just send the data to a remote master system (the portal), where all further processing takes place. This requires highly reliable measurement devices and a robust method of registering them in the system; at the same time, it provides two significant advantages. All configuring and setting up is performed at a single place – in the central SensDesk portal. There is no need to configure each remote device separately, which might require creating tunnels through the Internet to each device. Anyone who has tried to make their data at home accessible over the Internet knows that setting up the required routing at the home gateway (e.g. modem) is not always a straightforward task. And while it is relatively easy to set this up for one device, it can become very complex for multiple devices. Simple single-purpose devices, such as SD-Devices or NB-devices, connect to the server automatically without the need to configure any tunnels.

Smart devices, by their nature, need to be installed by an expert who, in addition to the intended application, also understands computer networks, address translation, and so on. Such people are expensive to hire; moreover, they may not be always qualified and authorized to work on the equipment to be monitored. As a result, the installation may need two people – a technician installing the sensors and an engineer configuring the monitoring device. On top of that, if the installation is done at a customer’s premises, the customer’s IT department may need to be involved, too. If you need to monitor one rack, it is possible to fine-tune the settings and, with the help of the IT team, put in place remote access for possible reconfiguration. A large installation can use a virtual LAN (VLAN) to simplify the situation. However, in case of many devices at different physical locations, the situation becomes complex and the advantages of simple single-purpose devices quickly become an important factor.

Simple single-purpose devices send data actively to a remote server, thus minimizing the risk of problems with the installation.

Smart devices that allow connecting sensors and detectors to buses can save hardware costs but rigorous testing and documentation is needed. Without it, it will be very difficult to troubleshoot e.g. swapped sensors in full operation. Therefore, simple single-purpose devices make things much easier. These devices actively send data to the remote server; instructions for the installation crew can be as simple as “plug the brown sensor into jack 1 and the white sensor to jack 2”, minimizing the risk of errors.

In case of M2M communication, the communication port must always remain open on the target router / firewall, which requires the intervention of a network specialist.

Access to individual devices from the external network (Internet) is also uncomfortable with direct connections, as communication ports need to be open on the destination router / firewall (one port per device), which requires the intervention of a network specialist.

When SensDesk is used as an intermediary, there is a slight slowdown in communication, but there is no need to interfere with the network infrastructure, which increases the security of both the application and the rest of the network.

By using the portal solution for setting up the behavior, Saferange and other target application parameters, the security of not only the application but also of the rest of the network is again increased. This method is very user-friendly, and what is more important, it remains the same across different products.

Changing the device configuration

When it comes to reconfiguring the devices, the differences between simple and smart devices are similar as in the case of installation. The portal solution is simpler and faster to maintain. Moreover, a single experienced engineer can manage even very large systems.

M2M operation

When two devices need to cooperate, the solution must be chosen according to the particular application. Compared to all-in-one solutions, simple devices offer the advantage of easy scalability. However, a direct connection between two devices is always faster and more secure than an intermediate central portal. Due to the architecture of cloud solutions, when an action needs to be performed with an output of a device via the portal, it is necessary to wait until the device connects to the central server; this can take anywhere from tens of seconds to several minutes. On the contrary, Poseidon2 and Damocles2 devices can establish a direct connection between themselves and react within a few hundred milliseconds to a few seconds. However, if the devices are in different networks, such a connection requires special routing configuration; this may take significant effort or, in corporate networks, can be even impossible.

Suitable applications for smart devices

Smart devices, such as Poseidon2, Damocles2 or HWg-PWR, are ideal for use in critical applications where the reaction, such as the sending of a text message or switching an output, must be as fast as possible. These devices also keep track of the real time and maintain a time-stamped data log. Moreover, they support multiple communication protocols, such as SNMP, ModBus/TCP, MQTT and more; however, configuration is required for proper operation. They are, therefore, better suited for industrial applications or closed networks and systems.

Independence of the solution

The need for a truly independent monitoring is the strongest argument for using devices such as Poseidon2, Damocles2 or HWg-WLD (smart devices). These device can autonomously measure the monitored quantities, evaluate the measurements and, if needed, send alerts, turn on a back-up system or switch off the monitored equipment to prevent further damages. The only criterion here is the importance of the application and its purpose. To send e-mail alerts, all that is needed is a working connection to the Internet (a SMTP server); to send text messages, a HWg-SMS-GW3 in the same network can be used (some devices can also interface with a modem).

Any single-purpose device relying on cloud services or another server solution is dependent on Internet access. Such a topology introduces at least one element to the communication chain that the user does not have under control. For this reason, smart devices are better suited for critical applications, or for installations where a company policy prohibits the use of server-based or cloud services.

Suitable applications for single-purpose SD-Devices and NB-Devices

Simple single-purpose devices are primarily intended for larger installations in terms of their geographical scope or the number of sensors.
They are suitable for applications that encompass many small installations spread over multiple locations. They allow connecting a few sensors and detectors and thus enable simple installation. At the same time, they do not require any special configuration, apart from e.g. configuring the Wi-Fi in case of SD-Devices. All subsequent operations are performed in the SensDesk portal only, and can be done by a qualified person. The low per-device cost is an advantage when extending the system; it is sufficient to buy just the inputs or outputs that are needed.

NB-Devices are typically used at remote locations without electricity and internet..

Cooperation between smart and simple devices

Both technologies can be combined within a single solution. The SensDesk portal can be used as the unifying element for both monitoring solutions, combining their advantages. For example, smart devices can be used to measure values and simple devices to control remote outputs or watch for water leaks.

Aranet4 Innovative Wireless Indoor Air Quality Sensor with Display

Several studies have found that one of the main reasons for poor well-being is the high concentration of carbon dioxide (CO2) indoors. It makes people anxious, sleepy and unable to concentrate. The U.S. Environmental Protection Agency (EPA) studies indicate that indoor levels of pollutants may be even five times higher than outdoors. Another study from Harvard University demonstrated that a heightened CO2 concentration reduces the brain’s cognitive abilities by 50%. These are the core abilities your brain uses to think, read, learn, remember, reason, and pay attention. Therefore, it is very important to ensure sufficient air circulation in rooms where people stay for extended periods of time.

SensDesk IoT Portal – A unified monitoring center for HW group devices and sensors

HW group - Monitor and Remote Control

SensDesk IoT Portal – A unified monitoring center for HW group devices and sensors

SensDesk portal as a unified monitoring center

Create custom views and graphs, arrange devices into groups and view your sensor data in custom graphs. These are the basic SensDesk features. The new portal adds many functions for the administration of large-scale monitoring applications and sensor networks. At the same time, it unifies the communication with and control of all HW group devices, including the communication among them. SensDesk can be also connected to monitoring applications.

SensDesk IoT Portal – A unified monitoring center

When speaking of a Portal or a Cloud, most people think of a website with graphs or a remote repository that costs money. And it is often the case. However, SensDesk by HW group is not just a portal or a cloud; it is primarily a unified measuring and control center for HW group products. SensDesk gives a quick overview of sensor states, displays a history of measured values, and allows creating simple conditions to trigger alarm actions such as sending an e-mail or a text message or activating a remote output. Its main advantage is the unified presentation of information from many different sensors and detectors in a human-readable and a machine-readable form.

The SensDesk portal offers features for home users, small and medium-sized businesses (SMB), as well as large enterprises and corporations. For homes and small offices, it is often enough to monitor the current states of sensors and detectors, and to be able to download the past temperature or consumption values (or to receive an e-mail if a value is out of an allowed range). Larger clients put emphasis on the integration of independent monitoring with existing systems. This can be complex, and thus expensive, because different measuring devices provide data in different formats – either for legacy reasons, or due to the particularities of the measured quantities. In these cases, SensDesk provides the most value – it makes data from different sensors and devices available in a unified and serialized XML file format.

Basic SensDesk features

  • A simple and concise Dashboard provides an overview of only those sensors that are interesting for the user. Multiple custom Dashboards with different contents can be defined. For example, the IT department would only watch the data that is relevant for them, and so would the power engineers.
  • Independent Safe Ranges can be set for each sensor for the purposes of e-mail alerts. Support for HWg-SMS-GW3 in order to send alerts via text messages (SMS).
  • An overview of devices and sensors that can be sorted by the status (Normal, alarm, invalid) or by the unit of measurement.
  • Devices and sensors can be grouped according to their physical (Locations) or logical (Groups) place.
  • Graphs of measured values for individual values (sorted by the measured quantities) as well as for individual sensors; data can be exported to CSV, XML, PDF, SVG, PNG or JPG
  • Custom graphs combining different quantities can be created to watch for interdependencies.
  • Advanced user management with a simple administration can assign individual users only the permissions they need. Individual users are grouped under a Team.
  • Permission groups to assign users the rights to individual devices. While the User management restricts what the user can do, the Permission group restricts the resources that the user works with.
  • Export of current values to XML is available for all values belonging to a team as well as for individual dashboards and graphs, and provides for an easy integration with ERP systems.
  • SensDesk can be used either on the free platform operated by HW group, or on the customer’s premises using a virtual server.

There is no need to list the common features of all portals, such as the ability to display the readings from individual sensors and detectors and plot their history in a graph.

Supported HWg devices
