    Product Details

    Key Features

    Features:
    .Brand new Ultrasonic Sensor HC-SR04 Distance Measuring Module
    .Features 4-mode connections: VCC / trig (T) / echo(R) / GND
    .With electric frequency output signal from 0V to 5V
    .Has high precision up to 3mm
    .5VDC power supply
    .Detecting distance is from 2cm to 450cm
    .Module Working Principle:
    Adopt IO trigger through supplying at least 10us sequence of high level signal; The module automatically send eight 40khz square wave and automatically detect whether receive the returning pulse signal; If there is signal returning, through outputting high level and the time of high level continuing is the time of that from the ultrasonic transmitting to receiving
