Netvox R72616A – Wireless LoRaWAN PM2.5, Temperature and Humidity Sensor

Netvox’s wireless PM2.5, temperature and humidity sensor is a continuous monitoring system for ambient air dust, temperature and humidity levels. The device is in line with the LoRa protocol standard. The R72616A with PM2.5 dust 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.

Features

  • Wireless range of up to 10 km (depending on environment)
  • LoRaWAN Class A compatible
  • Frequency Hopping Spread Spectrum (FHSS)
  • Improved interference immunity
  • Improved power management for longer battery life
  • Encrypt-RF™ Security (Diffie-Hellman Key Exchange + AES-128 CBC for sensor data messages)
  • Over-the-air updates (future)
  • Third-Party online wireless sensor monitoring and notification system to configure sensors, view data and set alerts via SMS text and email (optional)
