ABSTRACT
With the in-depth popularization of smart home concepts, intelligent monitoring and control of home environments have become important directions to improve the quality of life and ensure living safety. Traditional home management methods rely on manual operations, which have problems such as delayed responses, high energy consumption, and insufficient safety, making it difficult to meet the needs of modern families for convenient and personalized life.
The cloud-based home remote monitoring system based on the STM32F103C8T6 microcontroller integrates D203S human pyroelectric sensor module, 5516 light monitoring module, DHT11 temperature and humidity sensor, GP2Y10 dust concentration sensor, SU-03T voice recognition module, matrix buttons, OLED display, ESP8266WiFi module and executive devices (door locks, curtains, ventilation equipment, humidifiers, fans, etc.), realizing automatic monitoring and remote intelligent control of home environments. The core functions of the system include: detecting human presence through the D203S module, combined with password verification to realize automatic door lock opening; detecting light intensity with the 5516 module, automatically closing curtains when the light is below the minimum value, and opening curtains when it is above the maximum value; monitoring temperature and humidity through DHT11, activating ventilation equipment when temperature or humidity exceeds the limit, and turning on the humidifier when humidity is below the threshold; using GP2Y10 to detect dust concentration, and linking ventilation equipment to operate when it exceeds the standard; supporting SU-03T voice recognition control to realize voice control of doors, curtains, fans, and dehumidification equipment; setting parameter thresholds and manually controlling peripheral switches through matrix buttons; using an OLED display to real-time show monitoring data, thresholds, and mode status; uploading data to Alibaba Cloud through the ESP8266WiFi module, supporting mobile phone remote parameter setting and peripheral control.
The implementation of this system effectively improves the automation and intelligence level of home environment management, reduces manual intervention, enhances living safety and comfort, provides an efficient and convenient smart home solution for modern families, and also offers a reference for the research and development of similar home monitoring systems, with high practical application value.
