Abstract
As urban industrialization progresses and socio-economic development accelerates, there is a growing demand for higher levels of comfort and convenience in people’s lives. Through in-depth research in technologies like artificial intelligence and sensors, this paper presents a microcontroller-based smart indoor air quality monitoring and control system. This system integrates various sensors and intelligent control features to provide a healthier and more comfortable living environment.System Functionality:Smoke Detection and Alarm: Employing an MQ-2 sensor, indoor smoke concentration is monitored. When it exceeds the preset maximum value, the system triggers audio-visual alarms, simultaneously activating fans and purifiers to effectively eliminate smoke pollution.PM2.5 Detection and Alarm: Utilizing a GP2Y10 sensor, indoor PM2.5 concentration is monitored. Once it surpasses the defined upper limit, the system issues audio-visual alarms and initiates fans and purifiers, enhancing indoor air quality.Combustible Gas Detection and Alarm: By employing an MQ-5 sensor, combustible gas concentration is monitored. If it exceeds the predetermined upper limit, the system triggers audio-visual alarms and starts fans and purifiers to ensure indoor safety.Harmful Gas Detection and Alarm: Utilizing an MQ-135 sensor, harmful gas concentration is monitored. If it exceeds the set threshold, the system issues audio-visual alarms and activates fans and purifiers, safeguarding indoor air quality.Formaldehyde Detection and Alarm: Using an MS1100 sensor, formaldehyde concentration is measured. When the value surpasses the defined upper limit, the system triggers audio-visual alarms and starts fans and purifiers to reduce formaldehyde content.Temperature and Humidity Sensing with Voice Prompts: The DHT11 sensor monitors indoor temperature and humidity. If the temperature surpasses the set upper limit, the system delivers voice prompts, cautioning users about sun protection and heatstroke. In cases of excessive humidity, voice prompts advise users to carry umbrellas.Manual Control and Mode Switching: Equipped with buttons, users can manually set sensor thresholds, control fans and purifiers, and switch operating modes, offering a more flexible control method.Display Screen Data Presentation: Integrated with a display screen, real-time sensor measurements and system statuses are shown, enabling users to comprehend indoor conditions.Bluetooth Data Transmission and Remote Control: Integrating a Bluetooth module, measurement data is sent to users’ mobile devices. Users can monitor indoor air quality, control fans and purifiers, and switch system modes through a mobile app, achieving remote control.Through these functionalities, the smart indoor air quality monitoring and control system creates a healthier and more comfortable living environment for users. It also provides multiple control methods to meet the diverse requirements of different users. The system’s design and implementation will offer urban residents a higher quality of living experience.
