CO2, temperature and humidity sensor for Indoor Air Quality monitoring. IoT connected with LoRaWAN.

  • Battery powered3 
  • Three sensors in one housing: CO2, temp and RH 
  • LoRaWAN certified, IoT connected using the leading radio interfaces on the market 
  • Industry leading security solution with cryptographic co-processor 
  • Periodic measurement reports and adaptive reporting 
  • Remote indoor air quality monitoring through the cloud-based web portal, app or integration with HVAC control systems 
  • No calibration needed 

Senseair ExploraCO2 is a LoRaWAN certified, advanced and versatile 3-in-1 sensor, designed for installation in the air-conditioned zone. It measures CO2 concentration, temperature and relative humidity in the ambient air accurately without need for additional compensation. Adapting reporting when CO2 level changes more than 100ppm (higher than 750ppm). The data is encrypted and securely transmitted via LoRaWan to a cloud service. You can either use our dashboard service to display the data or design your own user interface utilising the open API. 

Senseair ExploraCO2 combines all the necessary elements for effective climate control in commercial office buildings, hospitals, hotels, schools and other facilities. Using CO2-monitoring for demand control ventilation (DCV) allows healthy, comfortable and cost-effective environments for the occupants. Simple and easy to install without any wires, makes the Senseair ExploraCO2 ideal for retrofitting in existing buildings.
