Sharp IR Proximity and Range Finder Sensor (15-150 cm) Microscope Matrix Keypad 16 switches areIntroduction : Sharp IR Proximity (GP2Y0A02YK0F) is an IR sensor useing infrared wave to measure distance. The output of the sensor is analog voltage, which can be read easily by microcontrollers ADC converter. This sensor can be used in industry and especially in robotics. The efficient range of this module is 15 to 150 cm. Infrared is sent out by the sensor which bounces off objects. The analog voltage that is returned determines how close the
