Design of Smart Home Environment Monitoring System Based on STM32

In order to improve the safety, convenience and comfort of the home, this paper designs a smart home environment monitoring system based on the STM32 microcontroller. The design adopts STM32F103ZET6 microprocessor as the core, and collects indoor environment information by temperature and humidity, photosensitivity, air quality, flame and other sensors. Wi-Fi module is used to complete the communication between the device and the cloud platform. With the help of LCD display and mobile phone APP to display the indoor environmental information in real time, when the indoor environmental parameters are abnormal, the system will automatically alarm, through the buzzer, screen prompt alarm, and the mobile phone will also send out the corresponding prompt message. Experiments show that the system can effectively realise remote monitoring of the environment, with good compatibility of system modules, low cost, easy operation and strong scalability, and has certain application value.
