Sharp GP2Y0A02YK0F is an analog distance measurement sensor using the triangulation method, which uses infrared light reflection. It is practically insensitive to the reflection coefficient of the observed object. Can be used as a presence detector.
The analog output signal is inversely proportional to the distance - the greater the distance, the lower the output voltage. The sensor has only 3 leads: Vcc - power supply, GND - ground and Vo - output voltage, which can be connected to the INP1 Lan Controller. According to the manufacturer, the supply voltage range is 4.5-5.5V, however, the sensor also works when powered with 3.6V from the Lan Controller, but you should take into account the less linear characteristics and lower output voltages. Sensor sold with visible connection cable.
