Real time detection of a water immersion sensor that can detect water leakage in the environment in real-time. When water immersion is detected, the detector will send an alarm signal to the host and report the information to the user's mobile phone. When the water level at the detection point reaches 0.5mm, the water intrusion sensor will report the water condition. Scene linkage is achieved through a mobile app to pre-set security scenarios. Once the monitored water level reaches the preset height, a remote alarm will be issued. When the warning water level is reached, the linkage gateway will issue a local sound and light alarm, and the mobile phone will receive an APP push reminder to notify you in a timely manner. The mobile phone can close the water outlet through a remote solenoid valve The new detection adopts advanced detection modules and real-time water sensing. When the accumulated water flows through the two poles of the probe, an alarm message will be immediately sent to the gateway. Long battery life: The battery can provide power for 1 year (if reminded 20 times a day) The multi scenario application leak detector can work normally in houses, hotels, shops, offices, and apartments. Protect every moment. We need a hub. This product is only applicable to Tuya Gateway.
