Introduction :
Sharp IR Proximity (GP2Y0A21YK0F) is an IR sensor useing infrared wave to measure distance.The output of the sensor is analog voltage, which can be read easily by microcontroller’s ADC converter.
This sensor can be used in industry and especially in robotics. The efficient range of this module is 10 to 80 cm.
Infrared is sent out by the sensor which bounces off objects.
The analog voltage that is returned determines how close the nearest object is. The closer it is, the higher voltage is returned.
