Descriptions:
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:
۱٫ Onboard STM8S103 high performance microprocessor
۲٫ With digital tube display
۳٫ Serial port data output
۴٫ Valid Measurement Distance: 3-400cm
۵٫ Display Unit: cm
۶٫ Max Error: 5V
Hardware Introduction:
۱٫ Board Size: 24.2*35.1mm
۲٫ VCC, GND: 5V power interface
۳٫ ۲٫۵۴mm White Socket: 5V power interface
۴٫ TX: module serial port transmit pin
۵٫ RX: module serial port receive pin
۶٫ NRST, SWIN: preset STM8 program download port
Usage:
۱٫ The measurement distance can be displayed via digital tube and serial port Digital Tube Display: directly plug in the ultrasonic module, connect 5V power
۲٫ 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:
۱٫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
۲٫Valid Measurement Distance: 3-400cm; if longer than this range, it will lead to incorrect data or 000 display
