WiFi Liquid Level Monitor Sensor | Smart Tank & Liquid Level Monitoring

The Tuya WiFi Ultrasonic Liquid Level Sensor is a smart, app-connected fluid level monitoring solution designed for residential, commercial, and light-industrial applications. Using ultrasonic distance measurement, it accurately reports liquid levels without direct contact with the fluid.

Integrated with the Tuya Smart / Smart Life platform, the sensor allows users to view tank levels remotely, set alarms, and automate actions such as pump control (optional configuration) directly from a smartphone or tablet.

With ±0.02 m accuracy, an IP65 enclosure, and a wide operating temperature range, this sensor is well suited to water tanks, rainwater systems, sumps, storage vessels, and other non-hazardous liquid applications. Powered via a 100–240 VAC to 5 V DC adaptor, it supports continuous monitoring without battery maintenance.
