Arduino Sharp IR Sensor - GP2D12




 
Specifications :

1、Measuring range : 10 to 80 cm

2、The maximum allowable Angle : > 40 °

3、The power supply voltage : 4.5 to 5.5 V

4、The average power consumption : 35 mA

5、Peak power consumption : about 200 mA

6、The frequency of updates/cycle : 25 Hz/40 ms

7、Analog output noise : < 200 mV
Arduino take six channel 10 ADC with itself, so we can directly connect the GP2D12 sensor with Arduino analog interface, and read the feedback value of this sensor.
 
According to the official manual, it is known that the output of the GP2D12 is 0.4 V ~ 2.4 V analog signals, corresponding 10 ~ 80 cmkjtance, output  is inversely proportional to distance, and nonlinear .

Test Code : ( Just for referring )

int i;
int val;
int redpin=0;
void setup()
{
  pinMode(redpin,OUTPUT);
  Serial.begin(9600);
}
void loop()
{
  i=analogRead(redpin);
  val=(6762/(i-9))-4;
  Serial.println(val);
}


 
Now you can watch the distance value in the window of Arduino 0021
