The Dragino LWL02 is a compact, low-power LoRaWAN Water Leakage Sensor (EU868) designed to detect water leaks and provide remote alerts through a LoRaWAN network. It detects the presence of water between two external metal probes and transmits leak events to the connected LoRaWAN network server.
Ideal for indoor applications, including basements, kitchens, bathrooms, utility rooms, data centers and HVAC installations, the LWL02 helps identify water leaks early and reduce the risk of water-related damage.
The sensor supports event-triggered and periodic data transmission, records the total number of water leak events and calculates the duration of the most recent leak.
Powered by 2 replaceable AAA LR03 batteries, the LWL02 is designed for long-term, energy-efficient operation, with an estimated battery life of 2 to 10 years, depending on network conditions, reporting frequency and battery type.
