[Use Anywhere] No cables required, place it anywhere you want. [Real-Time Detection] The water intrusion sensor detects water leaks in real time. When water is detected, the detector sends an alarm signal to the host computer and reports the information to the user's phone. When the water level at the detection point reaches 0.01m, the water intrusion sensor will report the water condition. [Scene Linkage] Enables preset security scenarios via the mobile app. Once the monitored water level reaches a preset height, an alarm will be issued remotely. [ Detection] Utilizes an advanced detection module for real-time water sensing. When water flows through the probe's two terminals, an alarm is immediately sent to the gateway. [Extremely Long Battery Life, Low Battery Alert] Low-power technology. Utilizing a high-performance, low-power microprocessor, the battery life reaches up to one year, eliminating the need for frequent battery replacements (e.g., 20 alerts per day) or the inability to send alerts due to low battery. [Multiple Applications] This water leak detector is suitable for homes, hotels, shops, offices, and apartments, ensuring protection at all times.
