Using Introduction:
1. The measurement distance can be displayed via a digital tube and serial port.
Digital Tube Display: directly plug in the ultrasonic module, connect 5V power.
2. Serial Port: plug-in ultrasonic module, VCC, TX, RX, GND respectively connects 5V, RX, TX, GND of USB to TTL module; serial port communication baud rate 9600, output format “D:XXXrn”; XXX represents distance, unit is cm.
Notice:
1. When measuring the distance, the area of a measured object should be no less than 0.5 square meters, and it should be smooth and has strong reflectivity; otherwise, it will affect the test result.
2. Valid Measurement Distance: 3-400cm; if longer than this range, it will lead to incorrect data or 000 display.
This Package does not include the HC-SR04 ultrasonic sensor.
Package Includes:
1 x Digital Display for HC-SR04 Ultrasonic Distance Measurement Control Board.
Digital Display for HC-SR04 Ultrasonic Distance Measurement Overview
The Digital Display for HC-SR04 Ultrasonic Distance Measurement Control Board is a compact, plug-and-play module designed to test and display distance readings from an HC-SR04 ultrasonic sensor. It uses an onboard STM8S103 microprocessor to trigger the sensor, calculate echo timing, and present results on a built-in digital tube display in centimeters.

Frequently Asked Questions
Does this board include the HC-SR04 sensor?
No, this product is the display and control board only. You need to mount a standard HC-SR04 ultrasonic module onto its Trig/Echo header.
How do I connect my HC-SR04 sensor to the display board?
Align the HC-SR04’s VCC, GND, Trig and Echo pins with the matching 4-pin header on the board, then supply 5 V DC to the 2.54 mm power socket. The onboard STM8S103 will handle triggering and echo timing, updating the digital tube display automatically.
Can I view readings on my PC?
Yes. The board outputs serial distance data through its UART interface at TTL level. Simply connect to a USB-to-TTL adapter or a microcontroller RX pin to log and display measurements alongside the built-in digital tube.
