Indoor sensors
Large swedish installation for smart energy use in University buildings
Akademiska Hus a customer of ELSYS and Nodeledge/Sensor online a partner of ELSYS is currently running one of Sweden’s most ambitious IoT projects in university buildings. With 20,000 sensors already in operation, this is the country’s largest LoRaWAN installation, and the project is only halfway. Once fully deployed, there will be around 40,000 sensors, along with 8,000 consumption meters using M-Bus and several smart controllable ventilation units and air handling systems. In total, approximately 250,000 data points will be collected and analyzed in real time via the Sensor-Online API.
The Sensors Making It Happen
- Elsys ERS CO₂ – measures carbon dioxide levels in classrooms and meeting rooms to monitor both air quality and actual occupancy.
- Elsys ERS Eye – motion sensors that detect whether rooms are empty or in use.
- TeraBee People Counter – installed at every entrance to track the number of people inside the building.
Together, these sensors provide a complete picture of occupancy and air quality, enabling precise control of ventilation, heating, and cooling – and shutting systems off where they are not needed.
Turning Data into Smart Building Control
By connecting all sensors and meters to Nodeledge’s IoT platform, Sensor-Online.se, developed entirely in Sweden and deployable on-premise, Akademiska Hus can:
- Optimize ventilation in real time based on CO₂ levels and occupancy.
- Automate heating and cooling depending on the number of people in the building.
- Analyze energy consumption per square meter and identify areas for efficiency improvements.
- Generate statistical insights for long-term planning and decisions about space utilization.
With 250,000 data points, it’s possible to take truly data-driven control over the entire property portfolio, saving both money and energy while improving comfort for students and staff. This is not just an example of smart IoT implementation in Sweden – it’s a flagship project showing how data, sensors, and automation can make university buildings both more efficient and sustainable.

Display sensors with real-time information
An ELSYS customer has installed multiple Display sensors across offices and apartments to ensure a healthy and comfortable indoor climate. Each apartment is equipped with a sensor that allows residents to easily view real-time temperature and air quality data, while the property owner can access the same information remotely. This setup provides valuable insights for maintaining optimal living conditions, reducing energy waste, and identifying potential ventilation or comfort issues early. It’s an effective way to collect data while also giving residents a clear, visual understanding of their indoor environment.
Monitoring with ERS LITE
Newsec, a Swedish partner of ELSYS, provides system solutions for real estate companies transitioning to smart buildings. They have installed 3200 ERS LITE and 250 ERS CO2 LITE sensors in apartments and offices. The project enables the property owner to monitor heating, detect moisture and ventilation issues, and resolve tenant temperature complaints more efficiently through real-time and historical sensor data.
Improving indoor air quality using dashboards
Arcade, an ELSYS customer, uses ERS CO2 sensors with the Alfons.io dashboard to visualize indoor air quality. The solution provides precise insights into CO2 levels, temperature, and humidity, helping improve air quality, space use, and employee well-being. Integrated with Philips Hue lighting, it signals high CO2 levels to encourage ventilation and maintain a safe, smart workplace.
Indoor air quality in lunch areas
An ELSYS customer has equipped their meeting rooms and lunch areas with ERS CO2 sensors to keep track of indoor air quality in spaces that see a lot of daily activity. By monitoring temperature and humidity as well, they can create a more consistent indoor climate, improve comfort, and lower energy costs.
Getting enough light?
With the help of the ERS, a client of ours was able to measure how much daylight they had in their office, among other values such as temperature and humidity.
Use this sensor to create the best indoor environment possible.
Outdoor sensors
Protecting Critical DNA Samples with Reliable 24/7 Monitoring
Will Sensors, partner of ELSYS successfully delivered a comprehensive IoT monitoring solution for a leading DNA and gene sequencing company, helping safeguard highly valuable biological samples and reagents stored in temperature-controlled environments.
The facility consists of a 7,000 m² warehouse with office areas, as well as two outdoor refrigerated storage containers. For the customer, maintaining the correct temperature at all times is mission-critical—each refrigerator or freezer can contain materials worth more than €100,000, making continuous monitoring essential.
The Solution
The installation is based on LoRaWAN technology and includes 53 ELSYS ELT-2-HP temperature sensors installed directly inside refrigerators and freezers, together with the IoT Systems platform for data visualization, alarm management, reporting, and notifications.
The ELSYS ELT-2-HP sensors operate reliably inside freezer compartments (-25°C to -18°C) and refrigerators (+4°C to +8°C), transmitting data every 15 minutes without any issues. Despite challenging conditions, communication performance remains strong, even in the outdoor refrigerated containers.
Key Benefits
The solution provides:
- 24/7 temperature monitoring
- Instant SMS, email, and mobile app notifications
- Early detection of open doors, cooling system failures, power outages, and seal icing
- Trend analysis for preventive maintenance
- Traceable and calibrated temperature measurements
- Automated scheduled reporting
- Dedicated IoT platform support
Proven Return on Investment
The project was implemented in 2022 with a total investment of approximately €25,000. Ongoing costs for the IoT platform, user accounts, and support are around €350 per month.
Since deployment, the system has prevented the loss of valuable materials on multiple occasions. According to Will Sensors, the solution has already paid for itself many times over by helping avoid costly incidents and ensuring the integrity of critical samples and reagents.
This project demonstrates how ELSYS sensors, combined with LoRaWAN technology and a powerful IoT platform, can deliver reliable monitoring and peace of mind in environments where every degree matters.
Measuring snow depth
YLLÄS, a customer of ELSYS, has successfully deployed our industrial sensor ELT2 ULTRASONIC in the winter landscapes of Lapland, Finland. In this northern region, characterized by extremely cold temperatures and substantial snowfall, the Ultrasonic sensor has proven instrumental in measuring outdoor temperature and snow depth. YLLÄS noted that it functions seamlessly throughout the year in Finnish Lapland, where temperatures can plummet to -35 degrees
Real-time water temperature measuring
In the areas around Umeå city, the local authority installed our ELT Lite with external temperature probes to measure the water temperatures. They were installed under jetties or in bell buoys in lakes or popular beaches.
The inhabitants of Umeå city could with this information decide where to go swimming, thanks to the real-time measurements of the water temperature.
Soil moisture measuring
A client working in agriculture using our ELT-2 with an external soil moisture sensor. This solution is ideal for having full control of the environment in the ground.
Optimize your work by using the information that the sensor gives you.
Getting enough light?
With the help of the ERS, a client of ours was able to measure how much daylight they had in their office, among other values such as temperature and humidity.

Measuring the distance
By placing the ELT Ultrasonic distance sensor like this, it is possible to measure the distance. In this case, it is the underground water level that is being measured, but we also have clients who use this to measure the level of trash in containers, depth of snow, and other similar cases.
