Design of indoor environment monitoring system based on Internet of Things and evaluation system

The system uses STM32F103CBT6 microcontroller as the main control module and is based on Internet of Things (IoT) three-layer architecture. The system realises real-time monitoring of the indoor environment status through a variety of sensors, and enables users to achieve remote monitoring of the indoor environment environment through WiFi wireless communication. By studying the quality evaluation system under the indoor environment monitoring system, it can not only achieve intelligent monitoring of the indoor environment, but also accurately and real-time achieve the comfort judgement of the indoor environment, enhance the user experience and improve people's quality of life and happiness index.
