And in Indirect Incidence, both the IR LED and Photo diode are placed in parallel (side by side), facing both in same direction. In that fashion, when a object is kept in front of IR pair, the IR light gets reflected by the object and gets absorbed by photodiode.
A photodiode is a transducer that takes light energy and converts it into electrical energy. If placed in a dark room, the photodiode is exposed to no light; therefore it creates no electricity. However, if light falls upon it, it takes the light energy and produces electric current in response.A photodiode conducts electric current directly proportional to the amount of light that falls upon it.ow to Connect a Photodiode to a Circuit. A photodiode operates in a circuit in reverse bias. This means that the anode connects to ground of the circuit and the cathode connects to the positive voltage supply of the circuit.
