Sharp GP2Y0A21YK0F IR Distance Sensor (10-80cm)

Sharp GP2Y0A21YK0F Analog Optical Distance Sensor

This Sharp distance sensor incorporates an infrared emitter, position-sensitive detector (PSD), and onboard signal processing circuit. Using optical triangulation, it produces an analog voltage output corresponding to object distance, making it immune to ambient lighting changes.
