Dragino Dragino LWL01 LoRaWAN Water Leak Sensor (EU868)
LWL01 is powered by a CR2032 coin battery, in a good LoRaWAN Network Coverage case, it can transmit as many as 12,000 uplink packets (based on SF 7, 14 dB). In poor LoRaWAN network coverage, it can transmit ~ 1,300 uplink packets (based on SF 10, 18.5 B). The design goal for one battery is up to 2 years. User can easily change the CR2032 battery for reuse. The LWL01 will send periodically data every day as well as for water leak event. It also counts the water leak event times and also calculates last water leak duration. Each LWL01 is pre-load with a set of unique keys for LoRaWAN registration, register these keys to local LoRaWAN server and it will auto connect after power on.
