"‘I want a house, facing the sea, spring blossoms…’ This poetic dream is often overshadowed today by high housing prices. Beyond these challenges, many people are now thinking about ‘smart home’ solutions. So, what exactly is a smart home? According to Baidu, it’s a system that integrates home-related devices using technologies like structured wiring, network communication, security systems, automatic control, and audio-visual tools. The goal is to create an efficient, safe, convenient, and comfortable living environment while promoting energy efficiency and environmental friendliness."
According to research reports, in 2018, there were 224 million households worldwide—accounting for 12% of global homes—and at least one smart home system was installed in each. Industry experts believe that smart home technology will eventually become as common in homes as TVs, refrigerators, air conditioners, mobile phones, and computers.
The following images provide a more visual experience. A recent report by Markets and Markets states that the global smart home market is expected to reach $122 billion by 2022, with an average annual growth rate of 14% between 2016 and 2022.
Today, millennials are becoming the main consumers in the housing market. Growing up in the digital age, they are more open to adopting and using smart home technology. This article explores DIY smart home projects, helping users make their homes more magical and modern.
**Option 1: A Complete Control System**
This system is based on STM32 chips from the Cortex-M3 architecture. It uses a modular design, offering miniaturized, intelligent, and networked control modules suitable for smart homes, embedded labs, student projects, and electronic competitions.
It includes components such as a smart home controller, smart socket, multi-function panel, dimmer switch, light sensor, temperature and humidity meter, touch screen, infrared detector, smoke and gas detectors, and more.
There are two control centers: one for the living room and kitchen, and another for the bedroom and bathroom. The design is shown below.
