This ultrasonic distance sensor is a practical module equipped with an open dual probe. It utilizes I2C communication and the standard Gravity PH2.0-4P vertical patch socket, making it compatible with 3.3V or 5V logic controllers, such as Arduino and Raspberry Pi. Designed with built-in temperature compensation, it provides reliable distance measurements ranging from 2 cm to 500 cm, with a resolution of 1 cm and accuracy of ±1%. Three selectable measurement ranges—150 cm, 300 cm, and 500 cm—allow for optimized performance depending on the application.
