How it works
Temperature, Humidity, and battery voltage are reported at regular intervals.
Immediate reporting if Alarm feature triggered.
LoRaWAN
The LoRa wireless technology in this device sends data over extremely long ranges at fixed intervals; default is one measurement every 20 minutes, but can be changed. It provides long range spread spectrum communication and high interference immunity whilst minimising energy consumption. In Australia, the AU915 (915 MHz) band is used, which does NOT need clear line-of-sight.
Decoder
See UBWH LoRaWAN Javascript Decoders. These decoders can be used in LoRaWAN Network Servers such as Chirpstack.
