When an infrared remote is used on the IR receiver, the device translates the signal and broadcasts it over RF. When the sensor is not exposed to any light at its working frequency, the VOUT output has a value equal to VS (power supply). The IR music transmitter works off a 9V battery, while the IR music receiver works off regulated 9V to 12V. In this project, we designed and implement a wireless optical transmitter and receiver system that established an audio communication at some distances with weak signal via infrared communication. Specifically, the receiver must pick up a noisy and attenuated transmission, selectively filter and amplify signals in the spectral regions around 24.3-MHz and 300-kHz, and ultimately demodulate the transmitted signal back to a recognizable audio signal. The outcome of this proposed work is to design and implementation an optical wireless system to transmit voice over a certain distance in laboratory. IR Transmitter and Receiver Circuit Diagram. The Audio signal will be transmitted through an IR LED from the transmitter circuit; the IR signals will be then received by a photodiode which will be placed on the receiver circuit.
