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. Test distance =

(high
level time * sound velocity (340M/S) / 2.

Note : This module is not suitable to connect with
electric power, if you need to connect this

module with electronic power,then let the GND terminal of
this module to be connected

first,otherwise, it will affect the normal work of the module
