Product Description

Feature:
There are 4 pins out of the module: VCC , Trig(control side), Echo(receiver),out (empty) GND .So it's a very easy interface for controller to use it ranging.
The all process is : pull the Trig pin to high level for more than 10us impulse , the module start ranging ; finish ranging , If you find an object in front , Echo pin will be high level , and based on the different distance,it will take the different duration of high level. So we can calculated the distance easily:
The test distance = (Duration of high level * speed of sound (340M/S))/2
