Grove ultrasonic sensor - distance measurement 3-350 cm, ±2 mm
Description
The Grove - Ultrasonic Distance Sensor is an ultrasonic transducer that uses ultrasonic waves for distance measurement. It can measure from 3 cm to 350 cm with an accuracy of up to 2 mm, making it ideal for distance measurement, proximity sensors, and ultrasonic detectors.
This module has an ultrasonic transmitter and an ultrasonic receiver, so it can be considered an ultrasonic transceiver. When the 40-kHz ultrasonic wave generated by the transmitter hits the object, the sound wave is reflected back and the receiver can receive the reflected ultrasonic wave. You only need to calculate the time from transmission to reception and then multiply it by the speed of sound in air (340 m/s) to calculate the distance from the sensor to the object.
Features
- Wide voltage support range: from 3.2 V to 5.2 V, compatible with 3.3 V/5 V and can be connected directly to the Raspberry Pi I/O
- Save I/O resources: only 3 pins are required; the transmit and receive signals share one I/O pin through time-division multiplexing
- Wide measuring range: 3 cm ~ 350 cm
- Easy to use: compatible with Grove port, plug and play
- Complete documentation and libraries for Arduino, Python, and Codecraft

What is Grove?
Grove makes connecting and experimenting easier and simplifies the prototyping process. No jumper wires or soldering are required. More than 300 Grove modules have been developed, covering a wide range of applications and meeting a variety of requirements. Not only the hardware but also the software is open source. We offer various Grove shields to enable connection to the Grove system with a range of microcontrollers.
