Ultrasonic Module HC-SR04 Distance Measuring Transducer Sensor (for Arduino) HC SR04.

1. Working Voltage : 5V(DC)
2. Static current: Less than 2mA.
3. Output signal: Electric frequency signal, high level 5V, low level 0V.
4. Sensor angle: Not more than 15 degrees.
5. Detection distance: 2cm-450cm.
6. High precision: Up to 0.3cm
7. Input trigger signal: 10us TTL impulse
8. Echo signal : output TTL PWL signal

1. VCC, 2. Trig(T), 3. Echo(R), 4.GND

Use method: Supply module with 5V, the output will be 5V while obstacle in range, or 0V if not.The out pin of this module is used as a switching output when anti-theft module, and without the feet when ranging modules.

Module Working Principle:
1. Give trigger input signal of at least 10us of high level at trig (T) pin.
2. The module automatically sends 40khz square wave and automatically returns pulse signal at echo (R) pin.
3. Distance can be calulated from the time difference between Input pulse and response pulse by following formula: Test distance = Time difference * sound velocity (340M/S)

Note : The module is ESD Sensitive, let the GND terminal of this module to be connected first.
