Ultrasonic Sonar Transmitter & Receiver Module

Low cost compact ultrasonic sonar (distance measuring) sensor with up to 4.5 meters range. 

A host microcontroller circuit determines distance by triggering the Ultrasonic Module and then measuring the echo time indicated by the pulse width output of the sensor.

How the module works:

(1) Module automatically sends eight 40kHz square wave and automatically detects for a signal return;
(2) IO trigger ranging to at least 10uS high signal;
(3) The signal return produces a high output once detected by the module.

Solving for Test distance:

Test distance = 1/2(time high x speed of sound (340m/s))
