Sensor technology

Elotec EloRa Smart Sensors

We offer maintenance-free sensor technology with up to 10 years of battery life and 10km range. The sensors are designed for harsh conditions and therefore can be used in everything from detached houses and commercial buildings to agriculture and industry.


With Elotec EloRa, the user gets a better basis for decision-making with sensor data. This helps streamline operations and contribute to economic growth with continuous monitoring of resources.


The sensor can prevent major damage by getting an alert before a fire develops. With service and maintenance alerts to your mobile, you get a full overview of all necessary numbers and avoid machine downtime. The system has high security and encryption of data.

EloRa Manager

An overview program with a simpel user interface. Can be customized to suit your needs, whether you want simple graphs or detailed reports. Can be used both on PC and mobile.


Possibility for multiple users, also provides the opportunity to allow individual users to monior only parts of the facility. For example, electricians can access the temperature sensor in electrical cabinets, so that they can take a look before an electrical inspection.


Set your own limit values or choose standardized limit values set according to Norwegian standards. Select notification SMS or Email whenever the values approach the limits set. 



EloRa Gateway

The central receives data from all the sensors and passes this on to the cloud solution. The only part of the system that requires internet and power access.

  • Possibility of using 4G, WIFI or wired network

CO2 sensor

Safety for animals and people. With a CO2 sensor, you receive an alert in the event of air quality pollution, so that measures can be taken. 
In addition to CO2 (carbide dioxide), the sensor measures temperature, humidity and air pressure. See battery level in real time. The sensor can be mounted in most places.
●    Withstands vibrations and harsh conditions. IP67. 
●    Very stable measurement between 400-5000 ppm.
Areas of use:
●    Ventilation systems in barns for warning of elevated CO2 levels to avoid dangerous situations for animals.
●    Monitor the silo for silo gas (mainly CO2), get alerts before dangerous situations arise. CO2 is devoid of smell and taste, but it is suffocating even in smaller concentrations.
●    Monitor CO2 levels when extracting tunnels, get alerts before a dangerous situation arises for the workers.

Soil sensor temp, moisture, conductivity

Get the status of the soil. Don't spend precious time analyzing the weather. Get exact numbers for when it’s time for action.
Measures soil moisture, soil temperature and conductivity of the soil. 

●    Withstands vibration and harsh conditions. IP66. 
●    Highly accurate measurement of both temperature(+-0.5'C) humidity (+-3%) conductivity (+-3%)
●    Very easy installation in soil.
Areas of use:
●    Monitoring humidity and temperature in the vegetable field or nursery, get alerts so that you can water at a very precise time, for optimal growth.

Ultrasonic level sensor

Get control of all warehouses, silos, tanks, dung cellars and other levels around the farm. Monitor what you need information about.
Accurately measures at a distance from measurable objects. The measurement is based on ultrasonic waves that are sent and reflected back from objects. The sensor can be placed in most places.

●    Withstands vibrations and harsh conditions. IP66. 
●    Highly accurate measurement of distance. (+-1%)
●    Very stable measurement between 0.3m to 10m.
Areas of use
Streamline day-to-day operations so you don't have to spend time trying to see if the grain silo needs to be refilled, the dung cellars/waste container needs to be emptied or if the tank needs to be filled.
