Check your tank level from your phone
Monitor your water tank through Tuya Smart or Smart Life. Mounted above the water, this ultrasonic sensor measures the distance to the surface without touching it, helping you follow water use and filling from your phone.
Dual-band Wi-Fi
Connect to a 2.4 or 5 GHz Wi-Fi network. The 5G model suffix refers to Wi-Fi frequency; no mobile SIM is required.
Up to 4 metres
Measure sensor-to-water distances from 10 cm to 4 metres and view the tank level in the app.
Adjustable level alerts
Set high and low thresholds and configure app notifications to match your tank and routine.
Contactless installation
Mount above the tank with the sensor facing the water. The sensor has an IP67 rating; protect its power connections separately.
