Module Working principle
Adopt IO trigger through supplying at  lea st 10us sequence of high level signal.
The module automatically sends eight 40khz sq uare wave and detects whether the returning pulse signal is received.
If there are returning signals,its throughput reaches high level,high level continuing takes the same time as from ultrasonic transmitting to receiving.
