Ultrasonic Distance Measurement module

Features : Onboard STM8S103 high-performance microprocessor. With digital tube display. Serial port data output. Valid Measurement Distance: 3-400cm. Display Unit: cm. Max Error: 5V. Board Size: 36 x 25 x 12 mm. VCC, GND: 5V power interface. 2.54mm White Socket: 5V power interface. TX: module serial port transmits pin. RX: module serial port receive pin. NRST, SWIN: preset STM8 program download port. 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:XXX\r\n”; 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.
