4PCS Wireless Smart Water Leak Detectors — Water Leakage Alarm Sensors for Home Security

Pack of 4 smart water leak detectors that monitor for moisture in real time. When the sensor senses immersion it immediately transmits an alarm signal to the host and pushes the alert to the user’s mobile phone. High sensitivity — the detector reports water when the level at the sensing point reaches 0.5mm. Network-connected for APP remote control, so you can check status and receive notifications from anywhere. Suitable for use in homes, hotels, shops, offices and apartments to provide continuous protection. For best results, place each unit flat on the surface where you need leak detection.
