    About Ultrasonic Range Sensor module:

    • This performance of the ultrasonic sensor distance measuring module is stable, measure the distance accurately. The module is with High precision, blind spots (3cm) super close. This module provides a full set of ranging process.

    • Model: HC-SR04;

    • Operating voltage: 5V DC;                                       

    • Static current: Less than 2mA;

    • IO logic voltage: 5V;

    • Sensor angle: Not more than 15 degrees;

    • Detection distance: 2cm~450cm;

    • High precision: Up to 3mm;

    • Mode of connection: VCC / trig(T) / echo(R) / GND;

    • 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 signals returning, through outputting high level and the time of high level continuing is the time of that from the ultrasonic transmitting to receiving.

    About 4-Digit Display module:

    • The module is based on a decimal point display module, it displays four digital tube (0.56 inches), only two signal lines can make MCU control four Digit 8-segment LED. Can be used to display decimal, letters and so on;

    • Can display the measuring distance by the ultrasonic range module;

    • 8 class adjustable brightness;

    • Operating voltage: 3.3~5.25V;

    • IO logic voltage: 3.3V or 5V.
