Ultrasonic Distance Measurement Control Board Rangefinder Digital Display + Ultrasonic Module HC-SR04

Ultrasonic Distance Measurement Control Board Rangefinder Digital Display for HC-SR04

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

Using Introduction:
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:XXXrn”; 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
