Abstract：With the continuous development of IoT technology, the demand for intelligent monitoring systems in student dormitories is increasing. This design proposes a student dormitory environment monitoring system based on Internet of Things technology, aiming to provide intelligent environmental control and safety warning by real-time monitoring of environmental parameters such as temperature, humidity, smoke, light intensity, and noise in the dormitory.The system uses STM32F103C8T6 microcontroller as the core controller. In terms of hardware design, the system integrates DHT11 temperature and humidity sensors, MQ-2 smoke sensors, light intensity detection modules, noise detection modules, and clock modules to achieve comprehensive monitoring of dormitory environmental parameters. The display module and WiFi module are respectively used for real-time display of monitoring parameters and transmission of data to the mobile phone. In terms of software design, the program collects and processes sensor data, judges and responds to environmental parameters, and outputs control signals by writing corresponding programs. Users can set environmental parameter thresholds and remotely control the on/off of fans, water pumps, and lighting equipment through the mobile app.The design and implementation of the student dormitory environmental monitoring system not only improves the comfort and safety of the dormitory environment, but also provides users with convenient environmental monitoring methods. Through intelligent environmental control and safety warning functions, the system can effectively prevent potential safety hazards caused by abnormal environmental parameters, which has important practical value and social significance.
