Waterproof Ultrasonic Distance Sensor (30~500cm)

The ultrasonic distance sensor is built for high performance and reliability in harsh environments. Utilizing sonar technology, it emits high-frequency sound waves and determines distance by measuring the time it takes for the echo to return. Its standout features include a robust, fully-sealed probe and high-precision measurements with temperature compensation, along with multiple versatile operating modes for diverse applications.

The sensor’s fully enclosed design shields it from moisture, dust, and environmental contaminants. This robust build ensures it functions effectively in harsh outdoor conditions and industrial settings, where typical sensors might fail. Unlike traditional open-element sensors, it excels in wet conditions without a dip in performance or durability.

Offering precision, the sensor boasts a 3mm resolution over a range of 30cm to 500cm. Its built-in temperature compensation feature adjusts for variations in sound speed due to temperature changes, maintaining consistent readings between -20°C and 70°C. With a 60-degree measuring angle, it detects objects effectively over a broad area.

The sensor is equipped with several operating modes for easy integration and adaptability. In PWM Pulse Width Output mode, a high pulse initiates measurement, ideal for direct microcontroller connections. UART Automatic Output mode manages measurements every 100ms, streaming data via UART, simplifying implementation. UART Controlled Output mode allows precise control of measurement timing via UART commands. Lastly, Switch Output mode turns the sensor into a proximity switch, activating its output pin upon detecting objects within a set distance.

This Version 2.0 sensor is a major upgrade from the SR04T model. It features an expanded operating voltage range from 3.3V to 5V, compared to the 5V-only SR04T, enhancing compatibility. Its multiple selectable modes offer increased flexibility and versatility for a wide array of applications.
