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
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
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.
