The main objective of this system is to preserve the quality of food stored in warehouses by continuously monitoring environmental conditions such as temperature and humidity, as these directly affect human health. The system integrates both hardware and software components. The hardware includes a DHT11 sensor, buzzer, ESP32 module, and LCD display, while the software is developed using Arduino C. The system continuously monitors the warehouse environment and generates alerts whenever temperature or humidity exceeds a predefined threshold through the Wi-Fi module. The real-time temperature is displayed on the LCD, and a buzzer is triggered in case of abnormal temperature detection, particularly for rice storage. Furthermore, IoT technology is employed to transmit data from the ESP32 module to a Telegram bot, enabling the administrator to receive emergency alerts and issue control commands remotely.
