Grove Ultrasonic Ranger Distance Sensor V2.0


The Grove – Ultrasonic Distance Sensor is a transducer that utilizes ultrasonic waves for distance measurement, covering a range from 3cm to 350cm with an accuracy of up to 2mm. It serves as an excellent module for applications such as distance measurement, proximity sensing, and ultrasonic detection.


This module incorporates both an ultrasonic transmitter and receiver, functioning essentially as an ultrasonic transceiver. Operating on a principle similar to sonar, it emits a 40KHz ultrasonic wave from the transmitter. Upon encountering an object, the sound wave is reflected back, and the receiver captures the reflected ultrasonic wave. By calculating the time between transmission and reception and multiplying it by the speed of sound in the air (340 m/s), the distance from the sensor to the object can be accurately determined.

In comparison to conventional ultrasonic modules like the HC-SR04, the Grove – Ultrasonic Distance Sensor integrates a single-chip microcomputer. Through time division multiplexing, the transmitting and receiving signals share a single pin, requiring only one I/O pin. Additionally, it supports both 5V and 3.3V, making it directly compatible with the 3.3V I/O of the Raspberry Pi. This is in contrast to the HC-SR04, which exclusively supports 5V and necessitates the use of a voltage conversion circuit when connected to the Raspberry Pi.
