CO2 Sensor
Available at August 2021

  • Compliance to LoRaWAN1.0.3

  • Integrated best-in-class 3 in 1 CO2 sensor with temperature and humidity sensor

  • Measurement range: 400 ppm –10000 ppm

  • Accuracy: ±(30 ppm + 3%)

  • IP40 equivalent

  • Easy operation: Simply wave in front of the device to receive a color-coded visual indicator of the overall air quality: Green (Good), Yellow (Fair), Red (Poor)

  • Built-in alarm buzzer with sound pressure level 80 dB(min)

  • Press-and-play installation

The CO2 sensor utilizes LoRaWAN connectivity to send the CO2 concentration data of the indoor environment. Measuring CO2 levels indirectly determines how many people are in a room, and ventilation can be adjusted accordingly. It can help administrators to maintain the suitable indoor air quality in the workplace for alertness and more productivity.
