Design of an indoor intelligent potted plant system based on STM32

In response to the problem that families love to plant potted plants indoors, but cannot take long-term care of them due to work or other reasons, resulting in short survival time of plants, a STM32 based indoor intelligent potted system is designed. The system uses STM32F103ZE as the main controller, loads sensors to collect air temperature and humidity, light intensity, soil moisture, and CO2 concentration, and displays them on the LCD screen of the system. In automatic working mode, compare the environmental data and threshold settings to the execution module of the automatic control system; In remote control mode, the system connects to the ONENET cloud platform through a WiFi module and uploads the environmental data collected by sensors to the cloud platform through WiFi. Users can monitor the current environmental data in real time through a mobile WeChat mini program and issue commands to remotely control various execution modules of the system. After testing, the system can automatically adjust the potted environment according to the system threshold in different environments, and can accurately respond to user commands. The system has good performance and strong practicality.
