ABSTRACT
This project presents the design of an environment monitoring physical project based on the STM32F103C8T6 microcontroller. The main goal of this project is to achieve real-time monitoring of temperature, humidity, and CO2 concentration, and to trigger audio-visual alarms and corresponding control measures based on predefined upper and lower limits. The specific functionalities include temperature and humidity sensing with display prompts for comfort, too low, too high, dry, and humid conditions. Additionally, CO2 concentration is measured with display prompts for suitable and too high levels, and when exceeding the upper limit, the system triggers audio-visual alarms and initiates ventilation.The system uses the DHT11 sensor to continuously monitor ambient temperature and humidity, displaying corresponding comfort levels such as comfortable, too low, or too high temperatures, as well as dry or humid humidity conditions. When the temperature and humidity exceed the preset upper and lower limits, the system automatically triggers audio-visual alarms to alert users of abnormal environmental conditions.Furthermore, the system utilizes the SGP30 sensor to measure CO2 concentration, displaying prompts for suitable and too high levels. When the CO2 concentration exceeds the preset upper limit, the system triggers audio-visual alarms and initiates ventilation measures to effectively control CO2 levels in the environment.The system is also equipped with a time calibration function, using the internal RTC (Real-Time Clock) to acquire and calibrate time through button inputs, ensuring accurate timekeeping.Users can set various threshold values through buttons to cater to different environmental requirements.Finally, the system utilizes an OLED display screen to present all measured data, providing users with intuitive information feedback.This environment monitoring physical project, through the control of the microcontroller and measurements of sensors, offers users a reliable system for real-time monitoring and controlling environmental parameters, demonstrating broad potential applications.
