GP2Y0A21YK0F
GP2Y0A21YK0F is IR distance sensor 10-80cm with analog output. The output / distance relations is like this:
have nice article about measuring distance with Arduino
the final code is:
int IRpin = 1; // analog pin for reading the IR sensor void setup() { Serial.begin(9600); // start the serial port } void loop() { float volts = analogRead(IRpin)*0.0048828125; // value from sensor * (5/1024) float distance = 65*pow(volts, -1.10); // worked out from graph 65 Serial.println(distance); // print the distance delay(100); // arbitary wait time. }
