APP remote control: If a water leak occurs, the WiFi water alarm will immediately send a notification to your mobile phone through the TUYA/Smart Life app and emit a sound signal at the same time. High sensitivity: Once the sensor touches the water, it will trigger a 130dB sound alarm, which will not stop even if it is not turned off or taken out of the water to attract attention. Easy to install: No complicated installation tools are required. The sensor can be easily installed with double-sided tape or screws. Widely used: Suitable for bathrooms, laundry rooms, water heaters, sewage pumps, sinks, dishwashers, kitchens, warehouses, garages, basements, aquariums, etc. Note: There is a "Settings" button on the side to quickly check the working status: the alarm will sound when pressed; the alarm will stop when released. In this case, it works normally. 2.4GHz WiFi support
