Necessary: The sensor makes use of 3.3V logic, so be certain that your Arduino board helps 3.3V UART or use a voltage divider to keep away from damaging the module.
Pattern Code to Learn Distance Knowledge
Right here’s a primary Arduino sketch to check communication:
void setup() {Serial.start(9600); // Communication with PCSerial1.start(115200); // Sensor default baudrate}
void loop() {whereas (Serial1.accessible()) {Serial.write(Serial1.learn());}}
Tip: In case your Arduino UNO doesn’t help Serial1, you can use the SoftwareSerial library for digital serial communication.
Troubleshooting Ideas
No information obtained? Double-check RX/TX strains (they should be crossed: Arduino TX to Sensor RX, and vice versa).Garbled output? Be certain baudrate matches the sensor’s default (usually 115200).Voltage mismatch? Think about using a logic stage shifter should you’re powering the sensor with 3.3V however utilizing 5V logic on Arduino.
