The Elsys ERS CO2 LoRaWAN® Sensor measures Carbon Dioxide and other indoor environmental factors including:

  • Temperature
  • Light
  • Humidity
  • Motion

Perfect for monitoring comfort and safe CO2 levels within smart buildings, smart homes, schools and warehouses this compact, minimalist sensor can be easily wall mounted in your chosen setting.

The Elsys ERS CO2 sensor can also be quickly and simply configured and retrofitted to your existing LoRaWAN® network.


  • LoRaWAN® Certified CM
  • CO2 sensor
  • Temperature sensor
  • Humidity sensor
  • Light sensor
  • Motion detection sensor (PIR)
  • Up to 10 years battery life
  • OTAA Configuration

The Elsys ERS CO2 sensor has an internal automatic calibration process. This procedure calibrates the sensor to set 400ppm to the lowest value that has been read in the last period of approximately 8 days. This means that in an 8 day period, the sensor must be exposed to fresh (well ventilated) air at least once for the calibration to work.
