The Dragino LWL02 is a LoRaWAN leak sensor. If water is detected between the two metal probes, the LWL02 indicates a water leak and sends an uplink via the LoRaWAN network to the backend. Here, the event is logged and, if necessary, an alarm is triggered. The LWL02 is powered by 2 x AAA batteries and is designed for long-term use. We recommend using lithium batteries to transmit 16,000 to 70,000 uplink packets. The batteries can be easily replaced thanks to the easy-to-open housing. The sensor also counts the water leak times and calculates the duration of the last water leak. The user can deactivate the uplinks for each water leak event; instead, the device can count each event and send the uplink regularly.
