HC-SR04P/SR04 Ultrasonic Sensor HC-SR04 Measuring Distance Sensor LED Display Module for Arduino Robot

<p>Digital Display for HC-SR04 Ultrasonic Distance Measurement Control Board adopts 8 bit MCU as the 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.</p> <hr /> <h4><strong>Features :</strong></h4> <ol> <li>Onboard STM8S103 high-performance microprocessor.</li> <li>With digital tube display.</li> <li>Serial port data output.</li> <li>Valid Measurement Distance: 3-400cm.</li> <li>Display Unit: cm.</li> <li>Max Error: 5V.</li> <li>Board Size: 36 x 25 x 12 mm.</li> <li>VCC, GND: 5V power interface.</li> <li>2.54mm White Socket: 5V power interface.</li> <li>TX: module serial port transmits pin.</li> <li>RX: module serial port receive pin.</li> <li>NRST, SWIN: preset STM8 program download port.</li> </ol> <hr /> <h4>Using Introduction:</h4> <p>1. The measurement distance can be displayed via a digital tube and serial port.<br />Digital Tube Display: directly plug in the ultrasonic module, connect 5V power.<br />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.</p> <h4>Notice:</h4> <p>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.<br />2. Valid Measurement Distance: 3-400cm; if longer than this range, it will lead to incorrect data or 000 display.</p> <hr /> <h4><strong>Package Includes: </strong></h4> <p>1 x Digital Display for HC-SR04 Ultrasonic Distance Measurement Control Board.</p>
