Pololu VL53L0X Laser Range Sensor, Range 2m

This sensor is a carrier/breakout board for ST’s VL53L0X laser-ranging sensor, which measures the range to a target object up to 2 m away. The VL53L0X uses time-of-flight measurements of infrared pulses for ranging, allowing it to give accurate results independent of the target’s color and surface. Distance measurements can be read through a digital I²C interface. The board has a 2.8 V linear regulator and integrated level-shifters that allow it to work over an input voltage range of 2.6 V to 5.5 V

Quick Spec

• Resolution: 1mm
• Maximum range: 2m
• Interface: I²C
• Minimum operating voltage: 2.6 V
• Maximum operating voltage: 5.5 V
• Supply current: 10mA
• Dimensions: 13 mm × 18 mm × 2 mm
• Weight: 0.5g

Pinouts

The VL53L0 uses ST’s FlightSense technology to precisely measure how long it takes for emitted pulses of infrared laser light to reach the nearest object and be reflected back to a detector, so it can be considered a tiny, self-contained lidar system.

Sample Code

/* This example shows how to use continuous mode to take
range measurements with the VL6180X. It is based on
vl53l0x_ContinuousRanging_Example.c from the VL53L0X API.
The range readings are in units of mm. */

#include <Wire.h>

void setup()
{
  Serial.begin(9600);
  Wire.begin();

  sensor.init();
  sensor.setTimeout(500);

  // Start continuous back-to-back mode (take readings as
  // fast as possible).  To use continuous timed mode
  // instead, provide a desired inter-measurement period in
  // ms (e.g. sensor.startContinuous(100)).
  sensor.startContinuous();
