Household Electric Fan Controller Design Based on MCU
Abstract: In this paper, the design is a home fan controller based on MCU, and the system is mainly composed of display module, temperature acquisition module, the keyboard control module, fan driver module and control system module. This design adopts DS18B20 and LCD1602 to achieve real-time detection and display of indoor temperature, at the same time control the fan speed according to the current temperature, and make the corresponding indicator light indicate the gear selection. This design uses C language to design program, and uses the Proteus and MCU box to test the simulation and experiment, and the simulation and test results show that the design realized the function of reservation, and it has the characteristics of energy saving, easy control and humanized.
