Intelligent Food And Grain Storage Management System For The Warehouse And Cold Storage

The Intelligent Food and Grain Storage Management System is designed to ensure optimal environmental conditions in warehouses and cold storage facilities to prevent spoilage and ensure the longevity of stored food and grains. The system utilizes an Arduino Uno microcontroller integrated with various sensors and control modules. An MQ135 gas sensor continuously monitors air quality, and when harmful gases are detected, a cooling fan is automatically turned on via a relay module to improve ventilation. In case of high temperature, detected by the DHT sensor, a Peltier cooling module is activated to maintain a cool environment essential for preserving perishable goods. A moisture sensor checks for dampness, and fire and LDR sensors provide fire safety and light condition monitoring, respectively. If any abnormal condition is detected by any sensor, an alert SMS is sent via the GSM module to the warehouse manager for immediate action. Furthermore, during low light or night conditions, detected by the LDR, LED lights are automatically switched on to ensure visibility and security. A buzzer and LCD display are used for the audio-visual alerts and system status display. This intelligent automation enhances food safety, reduces manual monitoring, and ensures quick response to environmental changes.
