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

  • LoRaWAN certified
  • IoT connected 
  • Cryptographic co-processor
  • Three sensors in one housing: PM, temp and RH 
  • Periodic measurement reports 
  • Cloud-based web portal, app or integration with HVAC control systems 
  • Powered via USB-cable 

Senseair ExploraPM2.5 is a LoRaWAN certified, advanced and versatile 3-in-1 sensor designed for installation in the air-conditioned zone. It measures the concentration of particles, temperature and relative humidity in the ambient air. 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 utilizing the open API. 

Senseair ExploraPM2.5 combines all the necessary elements for effective climate control in commercial office buildings, hospitals, hotels, schools and other facilities. Simple and easy to install, makes the Senseair ExploraPM2.5 ideal for retrofitting in existing buildings.
