With the advancement of modern agricultural technology, the monitoring and control of grain storage environments have become increasingly important. This paper proposes a grain environment monitoring system based on the STM32F103C8T6 microcontroller, aiming to achieve real-time monitoring and intelligent control of grain temperature and humidity to ensure the quality and safety of grain storage. The system utilizes waterproof DS18B20 temperature sensors and humidity sensors to monitor the temperature and humidity of the grain in real-time. It automatically controls based on preset temperature and humidity thresholds, and can be operated remotely via a smartphone application.The core functionalities of the system include temperature monitoring and control, humidity monitoring and control, manual setting of temperature and humidity thresholds, data display, and smartphone remote control. The DS18B20 sensor is used to monitor grain temperature. When the temperature exceeds the preset thresholds, the system automatically initiates heating or cooling operations and triggers sound and light alarms. The humidity sensor is used to monitor grain humidity. When humidity anomalies occur, the system activates sound and light alarms and conducts dehumidification operations during excessively high humidity.Users can manually set temperature and humidity thresholds using the device’s buttons, allowing for personalized control strategies. Additionally, the system is equipped with a display screen that shows real-time measurement data, enabling users to understand the status of the grain storage environment. By connecting to a smartphone app through a WiFi module, users can remotely access measurement data, set temperature and humidity thresholds, and control heating, cooling, and dehumidification operations. This enhances the intelligence level of grain environment monitoring and control.In conclusion, this paper presents a grain environment monitoring system based on the STM32F103C8T6 microcontroller that achieves precise management of grain storage environments through real-time sensor monitoring and intelligent control. This system is of significant importance in ensuring the quality, safety, and stability of grain storage, while also providing reliable technological support for agricultural production. With the continuous development of smart technology, this system holds promising prospects in the field of grain storage.
