Full documents and libraries provided for Arduino, Python, and Codecraft

Description

This module has an ultrasonic transmitter and an ultrasonic receiver so you can consider it 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.

How does the ultrasonic distance sensor work?

Here is a simple example of how an ultrasonic sensor works to measure distance:

Firstly, the transmitter (trig pin) sends a sound wave
The object picks the wave up, reflecting it back to the sensor.
The receiver (echo pin) picks it up

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.

Grove - Ultrasonic Distance Sensor vs HC-SR04

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.

Applications

Distance measurement
Ultrasonic detector
Proximity alarm
Smart car

Demo

We updated the support and example code to help you plug and play the ultrasonic distance sensor with Wio Terminal.

Work Well and Learn A Lot with this Ultrasonic Modules

I have used these in the past for the makeshift radar that can be found all over the internet as well as a "learning" robot car. IMHO they are accurate enough for hobbyist and those tinkering with arduino/raspberry pi platforms. I recommend these to anyone looking to expand their experience with programming and those tinkering with arduino and raspberry pi.

Excellent

Made a much better Radar system by processing an analog signal derived from an intermediate point. Checkout: https://www.instructables.com/id/Arduino-Analog-Ultrasonic-Radar/
