  • Advanced Remote Monitoring & Multi-Tank Support: Stay informed about your liquid levels from anywhere using the Tuya or Smart Life APP. This professional-grade sensor allows you to monitor up to 10 different tanks—including water, oil, and fuel—simultaneously. It integrates seamlessly into your smart home ecosystem, providing a reliable, long-range remote connection that turns any traditional tank into a fully managed smart system.
  • High-Precision Ultrasonic Sensing (4" to 157"): Equipped with an upgraded ultrasonic transducer, the ME201W delivers exceptional accuracy for depths ranging from 0.1m to 4m (10cm-400cm). Unlike mechanical floats, our non-contact sensor prevents clogs and corrosion. It is ideal for a wide variety of applications, including household water softeners, garden rain barrels, livestock troughs, and industrial sumps, ensuring a precise reading every time.
  • Enhanced 2.4G WiFi Stability & Easy Setup: Engineered for reliable connectivity, our sensor features an optimized 2.4G WiFi module with a signal range of up to 30 meters (98ft) in open areas. The "Plug-and-Play" installation ensures that the Tuya APP discovers the device instantly. Once connected, you can calibrate your "Liquid Maximum Depth" and mounting height in seconds, making it the most user-friendly level monitor on the market.
  • Rugged IP65 Waterproof & All-Weather Durability: Built to withstand harsh environments, the sensor features an IP65-rated waterproof housing with CE, RoHS, and REACH certifications. Designed for extreme reliability, it operates flawlessly in temperatures from 14°F to 158°F (-10°C to +70°C). Whether it’s the high humidity of a salt tank or the freezing temperatures of an outdoor cistern, this sensor is built for long-term outdoor and industrial durability.
  • Custom Smart Alerts & Automation Ready: Take full control of your supply with customizable high/low-level push notifications. Set specific thresholds to receive instant smartphone alerts before a tank runs dry or overflows. For advanced users, it is compatible with Home Assistant and Alexa automation—allowing you to trigger water pumps or automatically order salt/fuel when levels are low. Includes all necessary mounting hardware for a quick top-mount installation.
