EEG based home lighting system

This paper describes the EEG based home lighting system that uses voluntary eye blinks extracted from EEG signals to activate the lighting system. The system comprises of a PIC16F877A microcontroller and a lighting circuit. The EEG signals were first filtered to remove artifacts and then passed through the microcontroller which detected the four-second eye blinks using peak detection method. Once the eye blinks were detected, a relay was activated to turn on the light bulb. The functionality of the system was tested using the recorded EEG signals that were transferred from a computer to the system via a data acquisition card. It was found that the system could detect the eye blinks and switch on the lighting circuit successfully.
