A new control system via light-emitting diode (LED), lighting devices, is reviewed in this article.In order to transmit data, Visible Light Communication technology was used.Function block diagrams and schematic diagrams, of transmitting and receiving optical channels were used for the temperature control.Implementation of the developed system has been accomplished by the regulation of the onsite temperature control.Serial interface of data transmission has been applied in order to provide stable and reliable link via physical channels with the usage of LED lighting devices.According to the protocol of this interface, the transmitted data transforms into consecutive impulses in the accordance with the UART standard.The present work shows that asynchronous data transmission has been carried out via microcontrollers.In order to conduct the experiment presenting controlling possibilities via white LED lighting, a breadboard prototype with two modulestransmitter and receiverhas been created.The conducted measurements have shown that optical channel of data transmission has high reliability, while the illumination level does not change.There is no flickering and a comfortable lighting regime is provided.
