    Working Voltage : 5V(DC)
    Static Current: Less than 2mA.
    Output Signal: Electric frequency signal, high level 5V, low level 0V.
    Sensor Angle: Not more than 15 degrees.
    Detection Distance: 2cm-450cm.
    High Precision: Up to 0.3cm
    Input Trigger Signal: 10us TTL impulse
    Signal : output TTL PWL signal
    Mode of connection:
    VCC
    trig(T)
    ech0(R)
    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.
    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 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.

    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

    Package Included:

    1/3/5/10/20 x HC-SR04 Ultrasonic Module Distance Measuring Transducer (optional)

      Build quality is acceptable - works nicely - measurements are repeatable. Trig pin has pull-up resistor to 5V, and Echo pin is push-pull, so i recommend using level conversion when interfacing to e.g 3.3V FPGA (Sensor did not work well with 3.3 supply voltage) Price/Function ratio is good, almost excellent.

      I purchased 10 of these for several projects I am working on. At first I was worried because they were very affordable, I didn't expect much. Once they arrived, I could see the quality was fantastic. They are also very accurate, well exceeding my expectations. For anyone interested, I created an Arduino library for it and put on GitHub - https://github.com/dan-power/Arduino-HC-SR04

        Q: What is it?
        A:
        The HC-SR04 is a popular ultrasonic distance sensor. The sensor transmits high frequency ultrasonic sound which bounces off nearby objects. The sensor then listens for the echo, the difference in time from when the sound is transmitted and received, can be used to calculate the distance to an object within about 4 meters infront of the sensor.

        Q: these listing directions/ instructions dont make any sense, it says that "this module is NOT suitable to connect to electric power" but then its says that "if you need to connect this module to electric power to first connect the ground" so what is it, can it be hooked to electric power or not?!
        A:
        Allthey mean by that is that you first need to connect the ground pin before connecting the power 5v pin I have a few of these normally you first connect everything up before supply power so you should be ok as long as you do not provide more than 5v .
