ME202RSP 5m Remote Tank Liquid Level Sensor Solar Panel Tuya Mobile App Submersible LED Temperature Display Alarm Indicator

The ME202RSP Remote Tank Liquid Level Sensor is an advanced solar-powered wireless water level monitoring system designed for accurate and convenient remote measurement of water tanks, reservoirs, and storage systems. Built for smart home and outdoor applications, this intelligent device combines a submersible IP68 sensor, RF433MHz wireless communication, and a 2.4GHz WiFi gateway to provide real-time tank level data directly to your smartphone via the Tuya Smart App or Smart Life App.

Unlike standard wired level sensors, the ME202RSP features a solar-powered sensor module with a 6V / 450mA / 1.5W solar panel and a built-in 3.7V 1800mAh rechargeable 18650 battery, making it ideal for outdoor or remote tank installations where continuous power is not easily available. This greatly reduces maintenance and wiring complexity while ensuring reliable long-term operation.

With a measurement range of 0 to 5 meters and high accuracy of ±0.5%FS, the system delivers dependable liquid level readings for domestic, agricultural, and utility applications. The integrated LED display provides quick visual feedback for tank level percentage, sensor connection status, and temperature indication, making it easy to monitor local tank conditions at a glance.

Users can customize important settings such as installation height, maximum liquid depth, high-level alarm, low-level alarm, sensor ID pairing, and beep alarm on/off through the app. The device supports high and low level alarms, helping prevent overflow, dry running, and water shortages.

Designed for durability, the main device offers IP67 protection, while the submersible sensor is rated IP68, making it suitable for wet and demanding environments. This makes the ME202RSP an excellent choice for rooftop tanks, underground tanks, farm water systems, irrigation reservoirs, rainwater collection systems, and smart home water management.
