LRF3000A1 · 905 nm Laser Rangefinder Module

LRF3000A1 Arduino library and example sketch

Name: LRF3000A1 905 nm Laser Rangefinder Module
Brand: ERDI LASER
SKU: LRF3000A1

The Arduino library in erdi-lrf-drivers decodes the LRF3000A1 frame (8 B / 2 B at 115200 baud) and returns the distance in m. Use a hardware serial port; SoftwareSerial is not reliable at this rate.

Wiring

LRF3000A1 TX → Arduino RX1, RX → TX1, GND → GND, supply 3.3–5 V DC. Interface level: UART, 3.3 V TTL; check the level before connecting a 5 V board.

Example sketch

#include <ErdiLRF.h>
ERDI_LRF3000A1 lrf(Serial1);   // LRF3000A1

void setup() {
  Serial.begin(115200);
  Serial1.begin(115200);
  lrf.begin();
}

void loop() {
  if (lrf.readSingle()) {
    Serial.println(lrf.distanceMeters());
  }
  delay(100);
}
