Vendor:
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.

Highlighted Features

  • Wide measurement range: 3cm ~ 350cm
  • Save I/O resources: only need 3 pins, transmit and receive signals occupy one I/O pin through time division multiplexing
  • Easy to use: compatible with Grove port, just plug-and-play

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

Applications

  • Distance measurement
  • Ultrasonic detector
  • Proximity alarm
  • Smart car
