Abstract
As urbanization accelerates, indoor air quality has an increasingly significant impact on people’s health and quality of life. To address this challenge, this paper proposes and implements an intelligent indoor air quality monitoring and control system based on the STC89C52 microcontroller. This system is built on a foundation of multi-sensor technology, integrating sensors such as DHT11 for temperature and humidity monitoring, GP2Y10, MQ-2, MS1100, MQ-135, SGP30, etc., to detect concentrations of key pollutants such as PM2.5, smoke, formaldehyde, benzene, TVOC, etc. The monitoring data is displayed in real-time on the LCD1602 screen. The system also allows users to set alarm thresholds and manually control the operation status of fans and purifiers using buttons.To enhance user experience and convenience, the system integrates Bluetooth communication technology, enabling real-time transmission of monitoring data to a mobile app. Users can remotely monitor indoor air quality via their smartphones, obtain real-time insights into various metrics, adjust system settings, control fans and purifiers, and switch between different operating modes.Through a series of experiments, the system demonstrates remarkable performance. Its accurate air quality monitoring and automatic control functions effectively enhance indoor air quality. Therefore, this system offers an innovative solution for intelligent indoor air quality management, with wide-ranging practical applications.
Keywords: STC89C52 microcontroller; indoor air quality monitoring; multi-sensor technology; audible and visual alarms; Bluetooth communication; user experience.
