  • Photo Sensor Application Note
    of Operation of Optical Sensors The basic circuit of an optical sensor is shown in Figure 2-2.1(a). The anode of the LED is connected to the power line VCC via resistor RE and the cathode is grounded. Forward current IF is flowing through the LED and is emitting infrared light which is not visible
