LRF200H · 905 nm LiDAR Distance Sensor

LRF200H Arduino library and example sketch

Name: LRF200H 905 nm LiDAR Distance Sensor
Brand: ERDI LASER
SKU: LRF200H

The Arduino library in erdi-lrf-drivers decodes the LRF200H 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

LRF200H TX → Arduino RX1, RX → TX1, GND → GND, supply 9–36 V DC. Interface level: UART, IIC; check the level before connecting a 5 V board.

Example sketch

#include <ErdiLRF.h>
ERDI_LRF200H lrf(Serial1);   // LRF200H

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 LRF200H?

The published range is 0.05–200 m (90% reflectivity); 0.05–70 m (10% reflectivity) (The two source values remain bound to their stated target reflectivity.). 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 LRF200H use?

The published communication interface is UART, IIC.

What laser wavelength does the LRF200H use?

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

How much does the LRF200H cost?

The published single-unit price of the LRF200H is $250, falling to $100 per unit at the largest published quantity band. Prices include shipping and are ordered directly from erdilrf.com.
