Waterproof Ultrasonic Distance Sensor (30~500cm)

The ultrasonic distance sensor is a high-performance, weatherproof ultrasonic distance sensor designed for reliable operation in challenging environments. It operates on the principle of sonar, emitting high-frequency sound waves and calculating distance based on the time-of-flight of the returning echo. Its key differentiators are a robust, fully-sealed probe separate from the main circuit board, high-precision measurement with temperature compensation, and multiple versatile operating modes to suit a wide range of applications.

Robust Weatherproof Design

The core feature of the ultrasonic distance sensor is its fully enclosed and sealed ultrasonic probe. This design provides significant protection against moisture, dust, and other environmental contaminants, making it ideal for long-term outdoor deployment or in industrial settings where standard sensors would fail. Unlike conventional open-element sensors, it can reliably function in rainy conditions without compromising performance or longevity.

High-Precision Ranging Performance

Engineered for accuracy, the ultrasonic distance sensor provides a resolution of 3mm across its 30cm to 500cm detection range. Crucially, it incorporates built-in temperature compensation. This feature automatically adjusts for variations in the speed of sound caused by temperature fluctuations, ensuring consistent and reliable distance readings across its entire operating range of -20°C to 70°C. The wide 60° measuring angle allows for effective detection of objects within a broad area.

Versatile Operating Modes

To maximize compatibility and ease of integration, the SEN0208 offers several distinct operating modes, allowing it to adapt to different system architectures:

Note: This Version 2.0 model is a significant upgrade to the previous SR04T model. Key enhancements include a wider operating voltage range of 3.3V to 5V (compared to the 5V-only SR04T), providing greater compatibility. Additionally, it features multiple selectable operating modes for superior flexibility and versatility in various applications.
