New Arduino Sharp GP2Y0A21 IR Infrared Range Sensor + Cable

Read the distance of the object in front of your robot. The Sharp GP2Y0A21 IR Range Sensor takes a continuous distance reading and reports the distance as an analog voltage with a distance range of 10cm (~4") to 80cm (~30").

1、Measuring Detecting distance : 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
8、Less influence on the color of reflective objects, reflectivity
9、Line-up of distance output/distance judgement type ：
Distance output type (analog voltage) : GP2Y0A21YK
Distance judgement type : GP2Y0D21YK
Judgement distance : 24cm
(Adjustable within the range of 10 to 80cm [Optionally available])
10、External control circuit is unnecessary
11、Low cost

Code:
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);
}
Package included：
1X GP2Y0A21 Infrared Range Sensor
1X CABLE
