The Grove – Ultrasonic Distance Sensor is an ultrasonic transducer that utilizes ultrasonic waves to measures distance. It can measure from 3cm to 350cm with the accuracy up to 2mm. It is a perfect ultrasonic module for distance measurement, proximity sensors, and ultrasonic detector.
This module has an ultrasonic transmitter and an ultrasonic receiver so you can consider it as an ultrasonic transceiver. Familiar with sonar, when the 40KHz ultrasonic wave generated by the transmitter encounters the object, the sound wave will be emitted back, and the receiver can receive the reflected ultrasonic wave. It is only necessary to calculate the time from the transmission to the reception, and then multiply the speed of the sound in the air(340 m/s) to calculate the distance from the sensor to the object.
Compared with traditional ultrasonic modules HC-SR04, the Grove – Ultrasonic Distance Sensor integrates a single-chip microcomputer, and the transmitting signal and the receiving signal share one pin by time division multiplexing, so only one I/O pin is occupied. Another difference is that HC-SR04 only supports 5v voltage, while Grove – Ultrasonic Distance Sensor supports 5v and 3.3v. As we know, the Raspberry pi I/O only supports 3.3v. Therefore, Grove – Ultrasonic Distance Sensor can be directly connected to the I/O of the Raspberry Pi, but HC-SR04 needs to use a voltage conversion circuit.
What’s more, we provide full documents and libraries for Arduino, Python, and Codecraft so that you can use the Grove – Ultrasonic Distance Sensor with Arduino and Raspberry pi easily. Wide voltage range, single I/O pin, plug and play Grove connector, we try our best to make this module easier to use and reduce your work. This is exactly the philosophy of Grove: simple is the best. We hope you like it.
