Sharp GP2Y0A02YK0F is analog distance sensor using infrared light and adopt triangular method to measure distance. Thanks is not sensitive for reflectivity of the object. Can be used as proximity sensor also. Output voltage is proportional to distance to object. Thera are 3 connectors: Vcc - power supply, GND - ground and Vo - output voltage. However power voltage is in range 4,5-5,5V we tested proper work when supplied by 3,6V from Lan Controller. Output linerarity and output voltage range is worst then.
Sensor is offered with connection cable.
