Description:
The Waterproof Ultrasonic Distance Sensor Measuring Ranging Transducer Module is a high-precision, reliable solution for distance measurement in both indoor and outdoor environments. Designed to operate on a standard 5V DC power supply, it is fully compatible with popular microcontroller platforms such as Arduino, ESP32, Raspberry Pi, and other development boards.
This sensor uses ultrasonic sound waves at 40kHz to accurately measure distances by calculating the time taken for the sound pulse to travel to an object and reflect back. With a measurement range of up to approximately 4.5 meters, it delivers stable and consistent readings with high accuracy, making it ideal for a wide range of automation and robotics applications.
