Ⅰ. Real-time detection: 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 0.4mm, the water intrusion sensor will report the water condition. Ⅱ. Scene linkage: The preset security scene is realized through the mobile APP. Once the monitored water level reaches the preset height, the alarm will be raised remotely. When the early warning water level is reached, it will send out a local sound and light alarm, and the mobile phone will receive the APP push reminder to let you know in time, and the mobile phone can close the water outlet by the remote electromagnetic valve. Ⅲ. Detection: Adopt advanced detection module, real-time water body sensing. When the stagnant water flows over the two poles of the probe, an alarm message will be sent to the app immediately. Ⅳ. Long battery life, low battery reminder: The battery can supply power for 1 year (if the reminder is 20 times a day), and the battery is too low to promptly send an alarm notification. Ⅴ. Multi-scene application: The water leak detector can work normally in houses, hotels, shops, offices and apartments. Ⅵ.
