Netvox – R720A-Temperature and Humidity Sensor
Netvox – R720A-Temperature and Humidity Sensor
Description
Temperature and Humidity Sensor
The R720A is a wireless communication device that detects ambient air temperature and humidity. The R720A detects the temperature and humidity of the air and transmits the detected data to other devices via a wireless network using the SX1276 wireless communication module.
- LoRaWAN Class A compatible
- Frequency Hopping Spread Spectrum (FHSS)
- Improved interference immunity
- Improved power management for longer battery life
