Note : the module should be inserted in the circuit before been power, which avoid producing high level of misoperation;if not, then power again.

Module Working Principle:

1. Adopt IO trigger through supplying at least 10us 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 (340M/S) / 2.

Cost performance ratio is excellent. All 3 sensors arrived in good condition. But be aware: The HC-SR04 has a well-known bug (or is this really a feature???):
The sensor can stuck after measuring our of range. It delivers zero distance values permanently, even if something is quite close. There is a software workaround:
if (distance==0) {
pinMode(echoPin, OUTPUT);
digitalWrite(echoPin, LOW);
pinMode(echoPin, INPUT);
}

// OR this one

if (distance == 0 && digitalRead(ECHO_PIN) == HIGH) {
pinMode(ECHO_PIN, OUTPUT);
digitalWrite(ECHO_PIN, LOW);
delay(100);
pinMode(ECHO_PIN, INPUT);
}
}
