▪Pull the Trig pin to high level for more than 10us impulse.
▪The module automatically send eight 40khz square wave and automatically detect whether receive the returning pulse signal.
▪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 x sound velocity (340M/S)/2.
