Description


Ultrasonic ranging module for Arduino and other microcontroller projects

 
This module has a 40kHz ultrasonic transmitter and receiver pair mounted on the front of a small PCB along with the required control circuitry on the back. The module works by sending a short 40kHz square wave out and timing how long it takes to return to the module, you can then work out the distance it has traveled by knowing the speed of sound.
 
Voltage : 5VDC
Working Range : 20mm to 4500mm
Accuracy : 2mm
