Smart Home Light Based on Single Chip Microcomputer
Abstract
With the improvement of quality of life and the popularization of smart home concepts, the convenience and intelligence of home lighting have become important demands for people to pursue a comfortable life. Traditional home lighting control relies heavily on manual switches, which have problems such as inconvenient operation and single functionality, making it difficult to meet the lighting needs in different scenarios. For example, manual turning on of lights at night and inability to remotely control lighting status can affect the living experience. Therefore, it is necessary to develop an intelligent home light control system that is feature rich and easy to operate.
This design proposes an intelligent home lighting system based on STM32F103C8T6 microcontroller. The main functions of the system include: simulating the lighting of the bedroom, living room, and bathroom through three LED lights; Use three buttons to control the on/off of three lights respectively; Install D203S human pyroelectric induction module in the bathroom. When someone is detected and the 5516 photoresistor detects low light, the bathroom light will automatically turn on; The brightness of the living room lights can be adjusted through buttons; Set the bedroom light on time by pressing the button, and it will automatically turn off when the time is up. The OLED display screen will show the timer time in real time; Connect the ECBO2 Bluetooth module to the mobile phone to control the on/off of three lights and adjust the brightness of the living room lights; Control the on/off of three room lights and the brightness of the living room lights through the SU-03T speech recognition module.
The function of this smart home lighting system is to provide people with a convenient and intelligent home lighting solution. Through the integration of multiple control methods and automated sensing functions, the comfort and convenience of home lighting have been improved, meeting the lighting needs in different scenarios and enhancing the quality of life.
