Product Description

Working Voltage:DC 5V
Static State Current:5mA
Electrical Level Output: 5V high
electrical Level Output: at the end of 0V
Detection Angle:≤15°
Measurement Range:2cm~800cm
Interface Definition:VCC、Trig、Echo、Gnd
Using Method:Control port sends a high of more than 10us then wait for the high output at the receiving port.Once there being output can open the timer timing,when the port goes low timer value can be read,this is for the distance of time,can calculate the distance.Uninterrupted period measurement, mobile measurement value can be obtained.

Module Working Principle

1.Adopt IO trigger through supplying at least 10us sequence of high level signal.

2.The module automatically send eight 40khz square wave and automatically detect whether receive the returning pulse signal.

3.If there is signals returning, through outputting high level and the time of high level continuing is the time of that from the ultrasonic transmitting to receiving. 

4. Test distance = (high level time * sound velocity (340M/S) / 2.
