Feature: 1. Support for TUYA and connect to the for ZigBee gateway, ensure feedback instant, free tool installation, can share multiple family members, and care for family assets together. 2. When leakage occurs and contacts the detection probe, the sensor immediately issues alarm, when the device is detected, the device will notify you, and issue DIDI alarm sound. 3. With low power design, the device is substantially not consumed when the device is standby, and only the power is consumed when the alarm is turned. 4. The water leak sensor has the built‑in 3000mA rechargeable battery, which is durable and can be used for more than a year if it is fully charged. 5. When leakage occurs and contacts the detection probe, the sensor immediately issues alarm. The detection probe is 2mm from the ground height which can avoid false notifications. 6. Compared with traditional water dip sensors, this product uses a monomer design, which is flexible and convenient. At the same time, you can also achieve monitoring larger field through product's own 3.5 audio port.
