Paxcoo 62Pcs PCB Board Kit Includes 32Pcs Double Sided Prototype Boards, 20Pcs Header Connector and 10 Pcs Screw Terminal Blocks

There are 4 pins out of the module: VCC , Trig, Echo, 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:

Distance = ((Duration of high level)*(Sonic :340m/s))/2

Using IO trigger for at least 10us high level signal
The Module automatically sends eight 40 kHz and detect whether there is a pulse signal back
Static current: less than 2mA
he module performance is stable, measure distance accurately. SRF05, SRF02 ultrasonic ranging module and abroad comparable. Module precision, blind spots (2cm) super close, stable ranging success of this product according to market powerful! This module is completely Qian Yung GH-311 anti-theft module
