1 pcs : SEN0454 - Liquid Level Sensors Water Leak Detector

Water Leak Detector DFRobot Water Leak Detector indicates water leakage to minimize and avoid damage. The sensor is based on the integrated design of NO/NC. It aims to detect water leakage and water shortage. The sensor uses a relay output signal. When it is normally open and water touches the two probes, the built-in relay will be triggered. When it is normally closed and the water level is lower than two probes, the built-in relay will be triggered. Then, the alarm system will be turned on or the equipment in the house will be switched off.
