The Dragino LWL02 is a LoRaWAN leakage sensor. If there is water 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 an alarm is triggered if necessary. The LWL02 is powered by 2 x AAA batteries and is intended for long-term use. We recommend the use of lithium batteries to transmit 16,000 to 70,000 uplink packets. The batteries can be easily replaced through the easy to open housing. The sensor also counts water leak times and calculates the duration of the last water leak. The user can disable the uplinks for each water leak event, instead the device can count each event and send the uplink regularly.

The Dragino LWL02 is suitable for applications like Smart Buildings & Home Automation, Logistics and Supply Chain Management, Smart Metering, Smart Agriculture, Smart Cities, and Smart Factories.
The sensor uses 2 x AAA LR03 batteries, which are user-replaceable.
The sensor uplinks water leak events to an IoT server via LoRaWAN. It also sends periodic data, counts leak events, and calculates the duration of leaks.
The sensor sends data periodically and when a water leak event occurs.
Yes, the sensor can be configured remotely via LoRa Downlink.
The uplink payload includes status and battery information, MOD, the total number of water leak events, and the duration of the last water leak.
You can disable the event uplink feature using the AT command AT+DISALARM=1 or by sending a Downlink command 0xA701.
