Digital Display for HC-SR04 Ultrasonic Distance Measurement Control Board

The Digital Display for HC-SR04 Ultrasonic Distance Measurement Control Board is a compact and efficient module designed to test and measure distance using the HC-SR04 ultrasonic sensor.

• Powered by an onboard STM8S103 microcontroller, this board offers precise performance and supports both digital tube display and serial data output.
• Ideal for robotics , automation, and distance monitoring applications, it provides accurate measurements and a user-friendly design.
• Onboard STM8S103 Microcontroller is a high-performance chip that ensures efficient operation.
• Supports both digital tube display and serial port data output.
• Measures distances from 3cm to 400cm with a unit display in centimeters.
• Equipped with VCC, GND, TX, and RX pins for easy interfacing with power and serial modules.
• Small and lightweight for seamless integration into projects.
• Input Voltage: 5V DC Valid Measurement Distance: 3cm to 400cm Display Unit: Centimeters (cm) Communication: Serial port with baud rate of 9600 (output format: D:XXX\r\n) Board Size: 36mm x 25mm x 12mm Connect the HC-SR04 module to the board, power it with 5V, and view the measured distance directly on the digital display.
• Connect the module’s VCC, TX, RX, and GND pins to a USB-to-TTL module (5V, RX, TX, and GND, respectively).
• The measured distance will be output via the serial port in the format “D:XXX\r\n” (XXX is the distance in cm).
• For accurate measurement, ensure the measured object has an area of at least 0.5 square meters, is smooth, and has good reflectivity.
• Measurements exceeding 400cm may result in incorrect data or a "000" display.
