Design of Intelligent Home System Based on STM32

Abstract：This paper introduces a kind of intelligent home control system based on GPRS wireless network with stm32 single chip as the core. The system based on GPRS communication, wireless communication technology can be real-time monitoring of home temperature and humidity status, and can freely control the home electrical switch operation, the use of stm32 internal calendar to achieve effective time management of household appliances, while integrated light Acquisition circuit, can automatically switch the function of the window.

The design of the hardware circuit is simple, divided into controller module, GPRS module, relay control module, stepper motor control module and other five circuit modules, including controller based on cotex-m3 core 32-bit microcontroller STM32F103R8T6. GPRS module selection SIM900 module, human-computer interaction module selection OLED12864 module display data, independent keyboard as input device, relay control output control home appliance circuit switch. Finally, through the system test, the design of the realization of the functions include: the curtain motor to detect the current light intensity or humidity to achieve automatic opening and closing and local key control open and close, GSM SMS remote control relay opening and closing, indoor temperature abnormal GSM SMS notification
