Product Features
Intelligent LoRa Wireless & Tuya APP Remote Monitoring
Built-in industrial LoRa communication module features ultra-long transmission distance, strong anti-interference ability and stable signal transmission, suitable for complex industrial environments. Matched with the Tuya smart APP, users can remotely view real-time depth data, historical monitoring records and equipment operating status anytime and anywhere, and support remote parameter configuration, realizing unattended intelligent monitoring.
High Precision & Wide Detection Range
Supporting a professional detection range of 0.1m to 3m, the sensor solves the blind spot problem of short-distance measurement. Adopting optimized ultrasonic signal processing algorithm, it effectively filters environmental interference such as water surface fluctuation and air flow, ensuring accurate and consistent depth detection data for a long time.
Non-contact & Corrosion-resistant Measurement
Different from traditional float and pressure sensors, it adopts non-contact ultrasonic detection, no direct contact with monitored liquid. It effectively avoids equipment corrosion, scaling and damage caused by long-term contact with food and pharmaceutical liquids, greatly extending service life and reducing maintenance costs.
Low Power & Easy Compatibility
Standard 5V low-voltage power supply design is safe and energy-saving, compatible with most industrial control systems and smart monitoring equipment. The simplified circuit structure and stable hardware performance ensure low failure rate, plug-and-play deployment, and lower overall application cost.
Working Principle
The US-3L203 ultrasonic depth sensor works based on the ultrasonic echo ranging principle. The sensor probe actively emits high-frequency ultrasonic pulses, which propagate through the air and reflect back when touching the liquid surface. The built-in high-sensitivity receiving module captures the reflected echo signal, and the core chip accurately calculates the distance between the sensor and the liquid surface by measuring the time difference between ultrasonic transmission and reception, combined with the built-in temperature compensation algorithm to correct the influence of ambient temperature on sound velocity. Finally, the converted water depth data is uploaded to the cloud platform through the LoRa wireless module, and users can check and manage the data in real time via the Tuya APP, realizing continuous and automatic depth monitoring.
