LRF50VB · 905 nm Single-Point LiDAR Sensor

LRF50VB Arduino library and example sketch

Name: LRF50VB 905 nm Single-Point LiDAR Sensor
Brand: ERDI LASER
SKU: LRF50VB

The Arduino library in erdi-lrf-drivers decodes the LRF50VB frame (4 B / 2 B at 460800 baud) and returns the distance in mm. Use a hardware serial port; SoftwareSerial is not reliable at this rate.

Wiring

LRF50VB TX → Arduino RX1, RX → TX1, GND → GND, supply 3.3–5 V DC. Interface level: UART/IIC; check the level before connecting a 5 V board.

Example sketch

#include <ErdiLRF.h>
ERDI_LRF50VB lrf(Serial1);   // LRF50VB

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 LRF50VB?

The published range is 0.05–50 m (90% reflectivity); 0.05–20 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 LRF50VB use?

The published communication interface is UART/IIC.

What laser wavelength does the LRF50VB use?

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

How much does the LRF50VB cost?

The published single-unit price of the LRF50VB is $70, falling to $20 per unit at the largest published quantity band. Prices include shipping and are ordered directly from erdilrf.com.
