Resumen
In a communication system via visible light, and the use as lighting can transmit information using light intensity modulation at the transmitter and direct detection at the receiver, this type of system has free use range in the electromagnetic spectrum, as well as being more safe, since light does not exceed wall as radio signals. The implementation of this system uses low cost components such as a micro controller used in embedded systems, an LED and a photodiode. With the implemented system can check its operation in different situations, such as the influence of the distance transmissions, the different packet sizes, the frequency and angle of incidence of light between the transmitter and receiver.
