PRODUCT DETAILS

The Grove - Ultrasonic Distance Sensor is an ultrasonic transducer that utilizes ultrasonic waves to measure distance. It can measure from 3cm to 350cm with an accuracy of up to 2mm.  It is a perfect ultrasonic module for distance measurement, proximity sensors, and ultrasonic detectors. 

Features

  • Wide range of voltage support: in the range of 3.2V~5.2V, compatible with 3.3V / 5V, and can be directly connected to the Raspberry Pi I/O
  • Save I/O resources: only need 3 pins, transmit and receive signals occupy one I/O pin through time division multiplexing
  • Wide measurement range: 3cm ~ 350cm
  • Easy to use: compatible with Grove port, just plug-and-play

  • 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

    Cheap and Works Well
    Purchased these for a water depth application using an Arduino board. The work very well and seem quite capable of detecting the surface of a water column without issue. They can have some issues with multiple reflection points but this was expected. If I need that level of accuracy I would use a time of flight laser sensor.

    I got them on time and they work great.
    I got this for a small demo project. I started playing with them and they work as described. I have them hooked up to an Arduino and I have no complaints.

    Decent sensor, compatible
    The sensor was really good. I wish it had much more range which would have really helped me. Till now works really well in my DIYs. easy to operate. Would be a great by for beginners.

    Great for tinkering
    I bought these sonar sensors for a beginner project using the arduino. They are great for the price. There are plenty of instructions online on how to use these sensors. I believe they can also be used on the raspberry pi as long as you have the other required components.
