The Sharp GP2D12 is an analog distance sensor that uses infrared to detect an object between 10 cm and 80 cm away. The GP2D12 provides a non-linear voltage output in relation to the distance an object is from the sensor and interfaces easily using any analog to digital converter.

==Specification==
*Measuring range : 10 to 80 cm
*The maximum allowable Angle : > 40 °
*The power supply voltage : 4.5 to 5.5 V
*The average power consumption : 35 mA
*Peak power consumption : about 200 mA
*The frequency of updates/cycle : 25 Hz/40 ms
*Analog output noise : < 200 mV

char a,b;
void setup()
{
Serial.begin(9600); //
}
void loop()
{
int val;

Serial.print(b,DEC);//
Serial.println("cm");//
}
else Serial.println("over");//

tmp = analogRead(pin);
if (tmp < 3)return -1;
return (6787.0 /((float)tmp - 3.0)) - 4.0;
