HC-SR04 Ultrasonic Distance Measuring Transducer Sensor Module Arduino

Feature:

Voltage: DC5V
Static current: less than 2mA
Level output: high-5V
Level output: the end of 0V
Sensor angle: not more than 15 degrees
Detection distance: 2cm-450cm
High precision: up to 0.3cm
Connection: VCC, trig (control side), echo (receiving end), GND

 The basic principle of work:

    Using IO trigger for at least 10us high level signal,
The Module automatically sends eight 40 kHz and detect whether there is a pulse signal back.
If the signal back, through high level , time of high output IO duration is the time from sending ultrasonic to returning. Test distance = (high level time×velocity of sound (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

    Wire connecting direct as following:

    1. 5V Supply
2. Trigger Pulse Input
3. Echo Pulse Output
4. GND
