The Water Leak Sensor T1 detects water leak and flooding and monitors the status of water leak. When the water leak or flooding occurs, it sends an instant alert notification via the app. It also works with other smart accessories to automate your home.

Water Leak Sensor T1 makes use of the electrical conductivity of water. When two probes come into contact with water, a current loop is formed. At the same time, the sensor reports water leak/flooding status to the Hub and thereby triggers the alarm or turns on other smart accessories connected with it to execute relevant actions.

Water Leak Sensor T1 communicates with the Hub through Zigbee protocol wirelessly. Zigbee technology is a short-distance and low-power consumption wireless communication technology. As a communication protocol for smart home control system, it has become popular in recent years. Compared to other communication protocols, it has the following advantages:
1) Ultra-low power consumption;
2) Safer;
3) Ad hoc network, accommodating more accessories.

No, it can't. The Water Leak Sensor T1 must work with a Hub.

The installation of Water Leak Sensor T1 is simple and easy. You just need to place it on a surface that needs to be monitored.

Alarm can be triggered when the water level reaches up to 0.5 mm （0.02 inch).

The button of the Water Leak Sensor T1 is located at the center of the shell. Trigger the button by holding the top and bottom cover and pressing the "Water Drop" icon.

The Zigbee antenna of the Water Leak Sensor T1 is onboard antenna. It is right under the "Water Drop" icon.

The Water Leak Sensor T1 uses one CR2032 lithium battery. The output voltage of the battery is 3V. Normally, the service life of the battery is about two years (The actual service life depends on specific circumstances).
