Aqara T1 (WL-S02D) is a compact, advanced, and highly reliable smart water leak sensor. It is designed for maximum protection of your home or business premises against unexpected water damage. This device accurately detects leaks in real time. It achieves this by using highly sensitive inductive probes located at the base of the unit.
Why is the Aqara T1 a crucial leak sensor for your smart home?
As soon as the probes come into contact with liquid, this smart flood detector triggers immediately. It instantly sends an emergency notification to your smartphone. Furthermore, it can activate a loud local alarm on your Aqara Hub. Therefore, you can respond within the first seconds of an incident, even if you are far away from home.
The sensor is ideal for monitoring high-risk areas in any household. For instance, you can place it in the following locations:
- Underneath kitchen sinks and bathroom vanities
- Near washing machines or dishwashers
- In basements, boiler rooms, and spaces prone to moisture
Automation and advanced flood prevention
This sensor integrates perfectly into automated smart home scenes. For example, when paired with a smart water valve, the system can automatically shut off the main water supply as soon as moisture is detected. This advanced feature provides absolute peace of mind to homeowners. Consequently, it is also an ideal solution for property managers and landlords.
Energy efficiency and IP67 standard
Built with durability in mind, this sensor utilizes the advanced Zigbee 3.0 protocol. It ensures minimal power consumption. Thanks to this, a standard CR2032 battery can last for several years. Its robust design with an IP67 certification guarantees full protection against dust and water. In fact, the sensor will operate flawlessly even if it gets completely submerged.
Technical note for users
To receive mobile notifications and integrate this device into Apple HomeKit, Google Home, or Alexa, a compatible Aqara Hub is required. However, the physical setup itself is entirely wireless. It takes less than one minute. Simply place the sensor on any surface where a water leak risk exists.
