Dragino LWL02 – LoRaWAN Water Leak Sensor

The Dragino LWL02 is a LoRaWAN Water Leak Sensor. When there is water between the two metal probes, LWL02 indicates a water leak event and uplinks to the IoT server via the LoRaWAN network.

LWL02 is powered by 2 x AAA batteries and targets for long time use, these two batteries can provide about 16,000 ~ 70,000 uplink packets, which result in 2 ~ 10 years battery life. After the battery runs out, the user can easily open the enclosure and replace it with 2 common AAA batteries.

The LWL02 LoRaWAN Water Leak Sensor will send periodically data every day as well as for each water leak event. It also counts the water leak times and calculates the last water leak duration. Users can also disable the uplink for each water leak event, instead, the device can count each event and uplink periodically.

Each LWL02 is pre-load with a set of unique keys for LoRaWAN registration, register these keys to the LoRaWAN server and it will auto-connect after power on.
