With the progress of science and technology, traditional home can no longer meet people's needs, and smart home has gradually entered people's field of vision. In the paper, the embedded smart control system is designed with STM32 single-chip microcomputer as the core, equipped with high-performance sensor module, motor drive module, GSM short message sending and receiving module and TFT touch screen, and programmed with C programming language, realizing the functions such as touch screen control, curtain opening and closing, automatic light control, fire alarm, flammable and explosive gas alarm, short message sending and receiving, and display of sensor collected data, which not only meet people's basic requirements for living environment, but also improve the safety, convenience and comfort of home, and protect the living environment and save energy.
