Smart Ultrasonic Water Level Sensor for Tanks with Monitor Display - Wi-Fi and Tuya App
Monitor your tank water level intelligently and with complete precision
The wireless ultrasonic sensor puts tank control in your hands. Track water level and temperature in real-time via the included display or through your smartphone app, wherever you are.
Key Features
Precision Radar Technology
Utilizes ultrasonic technology to measure liquid levels with high accuracy of up to 0.02 meters without needing to touch the water, ensuring a longer lifespan for the sensor.
Simultaneous Dual Monitoring
Comes with a dedicated display showing the water level percentage and ambient temperature, with real-time synchronization with the Tuya Smart or Smart Life app on your phone.
Custom Smart Alarm System
Receive audible alerts from the display and notifications on your phone when the water level is low (to avoid pump dry-running) or high (to prevent overflow), with customizable alarm settings.
Long-Range Wireless Coverage
The sensor connects to the display wirelessly via 433MHz RF frequency with a range of up to 100 meters in open areas, while the display connects to home Wi-Fi to transmit data to your phone.

Setup and Installation Instructions
To ensure 100% accurate readings free from phantom reflections, please follow these installation guidelines:
- The sensor must be installed at the top of the tank perfectly vertical and parallel to the liquid surface.
- Avoid installing the sensor near the water inlet pipe (tank filling) to prevent false reflections caused by water flow.
- Do not install the sensor too close to the inner wall of the tank; the beam angle is ±15 degrees, and the reflection area must be free of obstacles.
- The required tank diameter depends on its height: for a 5m height, the diameter must be over 2m; for 3m, over 1.6m; for 2m, over 1.1m.
