This paper describes the design and implementation of an automated control system for grain storage temperature and humidity. Operations begin using a microcontroller, Arduino Uno, and DHT11 or thermocouple sensors, for real-time environmental conditions, whereas the temperature and humidity are controlled through a Peltier module and a USB spray humidifier, to give the ideal storage conditions. Another complementing feature is an I2C LCD, which visualizes real-time parameters for the users locally to monitor environmental conditions. Besides, the system also includes a Blynk app, which allows the users to monitor and control it through a phone interface from a remote location. The main function of this is to act as a standalone and inexpensive system, which is primarily aimed at reducing grain spoilage and ensuring quality. Test results have confirmed that it was able to provide applicable environmental control for various storage scenarios.

Another complementing feature is an I2C LCD, which visualizes real-time parameters for the users locally to monitor environmental conditions. Besides, the system also includes a Blynk app, which allows the users to monitor and control it through a phone interface from a remote location. The main function of this is to act as a standalone and inexpensive system, which is primarily aimed at reducing grain spoilage and ensuring quality.
