WebFeb 2, 2015 · Infrared receivers are also called as infrared sensors as they detect the radiation from an IR transmitter. IR receivers come in the form of photodiodes and phototransistors. Infrared Photodiodes are different from normal photo diodes as they detect only infrared radiation. The picture of a typical IR receiver or a photodiode is shown … WebIt is converted to an electrical signal by a microphone in the TX circuit. This signal is amplified by the LM741 audio amplifier and converted to an optical signal by switching. The voltage to the optical fiber is transmitted via a signal transistor. This optical signal is fed into the plastic fiber optic cable.
