Outdoor environment detection device based on the Internet of Things (STM32, APP, WIFI).zip

This article develops and implements a WiFi module based on STM32 on an embedded development platform. Combined with the above new concepts of the Internet of Things, it enables users to monitor the environment in real time through the network. This system enables users to grasp and control the situation they want to know in real time. Home information (temperature and humidity information, light information, PM2.5) is obtained through various sensors, and users can control this information on the Android interface.
