Smart Ethylene Management System : IOT Based Prevention of Premature and Artificial Ripening in Fruits

The IoT-based system for preventing faster ripening of fruits and vegetables successfully monitors and controls the key environmental factors ethylene gas concentration, temperature, humidity, and moisture that influence the ripening process. Through the integration of the ESP32 microcontroller with various sensors (MQ2 gas sensor, DHT sensor, moisture sensor, and load sensor), the system automates the management of fruit storage conditions in real-time. The project demonstrates that: Ethylene Gas Management: The system effectively detects increased ethylene levels using the MQ2 sensor and, in response, automatically activates the DC pump to spray an ethylene absorbent. This action helps slow down the ripening process and prolongs the shelf life of the produce.   Environmental Control: When temperature, humidity, or moisture exceed safe thresholds, the system triggers the DC fan to ensure proper air circulation, maintaining optimal conditions within the storage container. Real-Time Monitoring and Control: All sensor data are displayed on the LCD and transmitted to the Blynk IoT platform, allowing for remote monitoring and control via a smartphone. Alerts are generated in case of abnormal conditions, providing real-time updates to the user.   Overall, the system achieves its goal of reducing post-harvest losses due to premature ripening. By automating the monitoring and response to environmental changes, the system minimizes human intervention and enhances efficiency in the storage and transportation of fruits and vegetables. This solution offers a cost-effective, energy-efficient, and user-friendly approach to extending the shelf life of produce, making it highly suitable for use in agriculture and food storage industries.
