Smart Agro-Vehicle Freshness Monitoring System

In the modern agricultural sector, preserving the freshness and quality of harvested vegetables during storage and transport is critical. This project presents an IoT-based solution for monitoring the freshness of vegetables using Wi-Fi technology. The system integrates a network of sensors, including the DHT11 for measuring temperature and humidity, the MQ135 gas sensor to detect spoilage-indicating gases, and an ultrasonic sensor, which is repurposed to measure the quantity of fuel in vehicles. Additionally, an MPU6050 accelerometer sensor detects accidents The data collected from these sensors are processed using an ESP32 microcontroller, which triggers corrective actions such as activating a DC fan for ventilation or sounding a buzzer when spoilage is detected. This Project allows farmers or warehouse managers to receive real-time data from distant storage locations or vehicle systems. This IoT-based system ensures a cost-effective and reliable solution for monitoring environmental factors affecting vegetable freshness and vehicle safety. By addressing challenges in storage management and transportation, the system reduces post-harvest losses, improves supply chain efficiency, and enhances safety decision-making through real-time data access.
