Ultrasonic Distance Measurement Control Board Rangefinder Digital display for HC-SR04 8 bit MCU Diy Electronic PCB Board Module

Description:
This module adopts 8 bit MCU as main control chip, it can be applied in distance measurement, testing HC-SR04 ultrasonic module performance. And it supports serial port display and digital tube display

Function Features:

1. Onboard STM8S103 high performance microprocessor

2. With digital tube display

3. Serial port data output

4. Valid Measurement Distance: 3-400cm

5. Display Unit: cm

6. Max Error: 5V

Hardware Introduction:

1. Board Size: 24.2*35.1mm

2. VCC, GND: 5V power interface

3. 2.54mm White Socket: 5V power interface

4. TX: module serial port transmit pin

5. RX: module serial port receive pin

6. NRST, SWIN: preset STM8 program download port

Usage:

1. The measurement distance can be displayed via 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:XXX\r\n", XXX represents distance, unit is cm

Notice:

1.When measuring the distance, the area of measured object should be no less than 0.5 square meter, 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
