总结

一、简介

The laser ranging sensor module has low power consumption,体积小,安装方便.It is based on infraredLED发光,照射到被测物体后,返回光经过MCU接收,MCUCalculate the time difference to get the distance,直接输出距离值.
VL53LOXis a new generation of fully integrated sensors,Equipped with embedded infrared、Eye-safe laser,Advanced filters and arrays for ultrafast photon detection,longer measuring distance,Higher speed and precision.
The sensing capability of the laser ranging sensor can support various functions,Gesture sensing or proximity detection including various innovative user interfaces,扫地机器人、Obstacle detection and collision avoidance systems for service robots,Home appliance induction panel、User presence detection or power switch monitor for laptops,As well as drones and IoT products, etc.

三、测试方法

用USB2.0打印机数据线高速方口连接转接线与Arduino uno r3开发板连接在一起.Arduino uno r3开发板和VL53L0X V2Laser ranging module connection,如下图所示在这里插入图片描述

接线
5V —— VCC
GND —— GND
SCL —— SCL
SDA —— SDA
安装Arduino IDE 在这里插入图片描述 ,打开ArduinoIDE,先安装【IRremote】库,点击【项目】,再点击【新建】,输入代码,如下图所示

最后点击上传,如下图所示

代码如下：

/* This example shows how to get single-shot range measurements from the VL53L0X. The sensor can optionally be configured with different ranging profiles, as described in the VL53L0X API user manual, to get better performance for a certain application. This code is based on the four "SingleRanging" examples in the VL53L0X API. The range readings are in units of mm. */

#include <Wire.h>
#include <VL53L0X.h>

VL53L0X sensor;


// Uncomment this line to use long range mode. This
// increases the sensitivity of the sensor and extends its
// potential range, but increases the likelihood of getting
// an inaccurate reading because of reflections from objects
// other than the intended target. It works best in dark
// conditions.

//#define LONG_RANGE


// Uncomment ONE of these two lines to get
// - higher speed at the cost of lower accuracy OR
// - higher accuracy at the cost of lower speed

//#define HIGH_SPEED
//#define HIGH_ACCURACY


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

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

#if defined LONG_RANGE
  // lower the return signal rate limit (default is 0.25 MCPS)
  sensor.setSignalRateLimit(0.1);
  // increase laser pulse periods (defaults are 14 and 10 PCLKs)
  sensor.setVcselPulsePeriod(VL53L0X::VcselPeriodPreRange, 18);
  sensor.setVcselPulsePeriod(VL53L0X::VcselPeriodFinalRange, 14);
#endif

#if defined HIGH_SPEED
  // reduce timing budget to 20 ms (default is about 33 ms)
  sensor.setMeasurementTimingBudget(20000);
#elif defined HIGH_ACCURACY
  // increase timing budget to 200 ms
  sensor.setMeasurementTimingBudget(200000);
#endif
}

void loop()
{
    
  Serial.print(sensor.readRangeSingleMillimeters());
  if (sensor.timeoutOccurred()) {
     Serial.print(" TIMEOUT"); }

  Serial.println();
