买了两个sharp红外测距传感器GP2Y0A710K0F(100-550cm)和gp2y0a02yk_e(20-150cm)，买回来看到论坛中的帖子，距离的转换曲线有点复杂，就扔边上了。前天没事干就晚上搜了搜，居然找到了一个库函数，支持4种夏普的红外测距传感器。作者介绍说，他说肯据官方文档中的曲线做的拟合，精度我也不会测，接上线下载程序，觉得还是不错的，对于检测人的有无，及距离还是够用的。库中采样次数25次，中值滤波取中间值。传感器的电源和地之间串接440uF电容，用来稳定电源电压。
支持4种sharpIR传感器的读取，在示例程序中做相应的修改：
GP2Y0A02YK0F --> "20150"
GP2Y0A21YK --> "1080"
GP2Y0A710K0F --> "100500"
GP2YA41SK0F --> "430"

#include <SharpIR.h>

#define ir A0 //模拟输入引脚
#define model 100500    //传感器型号
// ir: the pin where your sensor is attached
// model: an int that determines your sensor:  1080 for GP2Y0A21Y
//                                           20150 for GP2Y0A02Y
//                                           100500 for GP2Y0A710K0F
//                                           430 for  GP2YA41SK0F
//                                           (working distance range according to the datasheets)

SharpIR SharpIR(ir, model);

void setup() {
  // put your setup code here, to run once:
  Serial.begin(9600);
}

void loop() {
  delay(500);

  unsigned long pepe1=millis();  // takes the time before the loop on the library begins

  int dis=SharpIR.distance();  // this returns the distance to the object you're measuring

  Serial.print("Mean distance: ");  // returns it to the serial monitor
  Serial.println(dis);

  unsigned long pepe2=millis()-pepe1;  // the following gives you the time taken to get the measurement
  Serial.print("Time taken (ms): ");
  Serial.println(pepe2);
