This is powered by a CR2032 coin battery. In a good LoRaWAN network coverage, it can transmit as many as 12,000 uplink packets (based on SF7, 14dB) and in poor LoRaWAN network coverage, it can transmit ~ 1,300 uplink packets (based on SF10, 18.5dB). One battery is estimated to work for about 1 year and you can easily change the CR2032 battery and continue using this sensor in your projects.
This water leak sensor will send periodical data including water leak events to the LoRaWAN network every day. It can also count the number of water leak events and calculate the duration of the last water leak event.
Each sensor is pre-loaded with a set of unique keys for LoRaWAN registration. Register these keys to the local LoRaWAN server and it will auto-connect after powering on.
This water leak sensor can be set up as follows in a LoRaWAN network:
