Abstract: Monitoring environmental conditions in storage facilities, especially for crops like ragi and wheat, is crucial for maintaining their quality and safety. Traditionally, manual methods for tracking temperature, humidity, air quality, and fire risks are labor- intensive and prone to errors. Our prototype offers a modern, automated solution using an ESP32 microcontroller integrated with various sensors. This system ensures reliable and continuous monitoring, with data logged to ThingSpeak and alerts sent via Pushbullet for immediate response, providing a cost-effective and efficient approach to managing storage environments.

Keywords: Environmental monitoring, ESP32, temperature and humidity, air quality, fire detection, automated alerts, data logging, cost-effective.
