HC-SR04 Ultrasonic Sensor Kit Distance Measuring Module 0.56 Inch Decimal Point 4-Digit Display Module Compatible for Arduino
Description
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.
