Abstract
In order to provide home intelligent control function for the elderly more efficiently and conveniently, this paper designed a smart home system controller based on raspberry PI with simple hardware structure and low development cost. The design is implemented by raspberry PI development board and python language, and the fatigue detection algorithm is implemented by OpenCV visual library, Dlib library and EAR algorithm. Through temperature and humidity sensor, infrared extended version, LCD display screen and other hardware intelligent control indoor environment. The test results show that the fatigue state can be accurately detected and the electrical control function can be realized. This design enhanced the intelligence of household control, and met the life demand of energy-saving convenience.
