基于STM32智能家居系统的硬件设计

Hardware Design of Smart Home System Based on STM32

本文主要介绍智能家居系统的硬件设计部分。本设计以STM32F429IG为核心,硬件系统设计部分充分利用直流电机、步进电机、传感器以及外部开关,使用不同LDO对各部分电路电压进行稳压。根据设计要求画出对应的PCB设计图,并使用SMD精准焊接,搭建电路后,联机调试,确保硬件能够安全运行,再通过程序的编写,最终实现自动报警、灯光照明控制、温湿度控制、空气质量测量、家用电器定时、窗帘自动控制等功能。

This article mainly introduces the hardware design part of the smart home system.This design uses STM32F429IG as the core.The hardware system design part makes full use of the DC motor,stepper motor,sensor and external switch,and uses different LDOs to regulate the voltage of each part of the circuit.It draws the corresponding PCB design drawing according to the design requirements,and uses SMD to accurately weld.After the circuit is built,it makes debug online to ensure that the hardware can operate safely.Then,through programming,the automatic alarm,lighting control,temperature and humidity control,air Quality measurement,home appliance timing and automatic curtain control are achieved.
