Netvox’s wireless LoRaWAN® PM2.5 air quality, temperature and humidity sensor is a continuous monitoring system for ambient air dust, temperature and humidity levels. The device works in line with the LoRa protocol standard.

The PM2.5 air quality sensor can be used to obtain the concentration of suspended particulates in air per unit volume and then the alert messages are sent to a centralised monitoring system via the LoRaWAN® protocol at pre-programmed intervals.


  • Wireless range of up to 10 km (depending on environment)
  • LoRaWAN® Class A compatible
  • DC Powered sensor with battery back up
  • Frequency Hopping Spread Spectrum (FHSS)
  • Improved interference immunity
  • Encrypt-RF™ Security (Diffie-Hellman Key Exchange + AES-128 CBC for sensor data messages)
  • Over-the-air updates (future)

We can supply third-party online wireless sensor monitoring and notification system to view data and set alerts via SMS text and email.

Ask us about our zero-touch provisioning service, this sensor can be supplied pre-configured and ready to go.
