LRF50H · 905 nm LiDAR Distance Sensor

LRF50H Arduino library and example sketch

Name: LRF50H 905 nm LiDAR Distance Sensor
Brand: ERDI LASER
SKU: LRF50H

The Arduino library in erdi-lrf-drivers decodes the LRF50H frame (4 B / 2 B at 460800 baud) and returns the distance in cm. Use a hardware serial port; SoftwareSerial is not reliable at this rate.

Wiring

LRF50H TX → Arduino RX1, RX → TX1, GND → GND, supply 9–36 V DC. Interface level: UART; check the level before connecting a 5 V board.

Example sketch

#include <ErdiLRF.h>
ERDI_LRF50H lrf(Serial1);   // LRF50H

void setup() {
  Serial.begin(115200);
  Serial1.begin(460800);
  lrf.begin();
}

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

FAQ

What is the maximum range of the LRF50H?

The published range is 0.05–50 m (90% reflectivity); 0.05–15 m (10% reflectivity) (The two source values remain bound to their stated target reflectivity. The source marks this parameter as measured at 25°C in an indoor environment.). A range figure is only comparable together with the target and conditions it was measured on, so the condition is listed next to the value.

Which interface does the LRF50H use?

The published communication interface is UART.

What laser wavelength does the LRF50H use?

The published wavelength is 905 nm; laser safety entry: Class 1.

How much does the LRF50H cost?

The published single-unit price of the LRF50H is $100, falling to $50 per unit at the largest published quantity band. Prices include shipping and are ordered directly from erdilrf.com.
