Main Content

Ultrasonic sensor module is used for measuring the distance between two objects. The sensor works on the principle similar to radar or sonar. The sensor produces the high frequency sound and evaluates the echo received back by the sensor. Sensor then calculates the time interval between sending the signal and receiving the echo to determine the distance between the objects. The Ultrasonic ranging module provides 2cm - 400cm non-contact measurement function, the ranging accuracy can reach to 3mm. The modules includes ultrasonic transmitters, receiver and control circuit. The working principle of the module is as follows: Set the trigger pin high for at least 10uS, then module automatically sends eight 40 KHz pulse and detects whether the pulse signal is back or not. The echo pin goes high and remains high till the echo is received (38mS Max). Calculations are as follow:

             Test Distance = (High level time X Velocity of the sound (340M/S))/2.

             High level Time=Timer count * Time period.
