Arduino take six channel 10 ADC with itself, the GP2D12 sensor can directly connect with Arduino analog interface, and get 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 .
Code:
char GP2D12;
char a,b;
void setup()
{ Serial.begin(9600); //}
void loop()
{int val;GP2D12=read_gp2d12_range(0);a=GP2D12/10;b=GP2D12%10;val=a*10+b; if(val>10&&val<80)
{Serial.print(a,DEC);//Serial.print(b,DEC);//Serial.println("cm");// }
else Serial.println("over");//
delay(50);}float read_gp2d12_range(byte pin)
{int tmp; tmp = analogRead(pin);if (tmp < 3)return -1; return (6787.0 /((float)tmp - 3.0)) - 4.0;}
Package includes:
1pcs Chinduino SHARP IR Ranger Sensor GP2D12
