This design project utilizes the STM32F103C8T6 microcontroller as the core controller to implement an intelligent classroom management system. The specific functionalities include:RFID Card Authorization: The system authorizes student cards using an RFID module, allowing only authorized cards to access the classroom. The system consists of two buttons, one for card authorization and the other for card deauthorization, along with two status LEDs. The red LED indicates unauthorized access, while the green LED indicates authorized access. The card numbers are stored in the AT24C02 chip.PIR Motion Detection: The system employs a PIR motion sensor module to detect the presence of individuals in the classroom.Light Dependent Resistor (LDR) Monitoring: An LDR is used to monitor the ambient light intensity in the classroom. If the light intensity falls below the predefined threshold and human presence is detected, the lights will automatically turn on.Temperature and Humidity Monitoring: The DHT11 sensor is used to measure the temperature and humidity values inside the classroom.Internal RTC for Time Synchronization: The system synchronizes time using an internal real-time clock (RTC) and sets the class start and end times. When the scheduled class start or end time is reached, a buzzer will sound for 3 seconds.Voice Recognition for Curtain Control: A voice recognition module allows users to control the curtains using voice commands. The curtains are simulated using a stepper motor.Remote Control and Configuration: Data can be remotely sent to a mobile device via a WiFi module. Users can configure the minimum light intensity threshold using the mobile app.Time Calibration and Light Setting: The system provides button functionality to calibrate the time and set the minimum light intensity threshold.OLED Display: An OLED screen is used to display the current time, temperature, and humidity information.This intelligent classroom management system combines various sensors and modules to achieve intelligent control and management of classroom access, lighting, temperature, humidity, time, and curtains through the control and processing capabilities of the microcontroller. Further improvements and expansions can be made to enhance user experience and the level of system intelligence.
