Netvox’s wireless air temperature and humidity sensor collects and transmits readings to give accurate measurements allowing you to monitor any changes in environment. The wireless sensor sends the alert messages to a centralised monitoring system via the LoRaWAN protocol at pre-programmed intervals.

Features:
- Wireless range of up to 10km (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)
- Battery Life of up to 5 years (determined by sensor reporting frequency and other variables)
- 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)
