WL03A-LB/LS LoRaWAN Su Kaçağı Sensörü

The Dragino WL03A-LB/LS is a LoRaWAN 1.0.3 Class A compliant water leak controller with rope-type sensor design. Deploy the sensor cable on floors and in enclosed spaces to detect water leakage with high sensitivity and report events to your IoT server via LoRaWAN. The device sends periodic data every 2 hours and triggers immediate notifications on water leak events, counting occurrences and calculating leak duration. Featured in IoTMarketi's multi-brand catalog, this controller is available for smart building, city, and industrial projects in Turkey via project quote request.
