Post-harvest losses of fruits and vegetables at the farmers level is a big concern. With the rising demand for fresh produce, effective cold storage is crucial to minimize post-harvest losses, maintain product quality, and ensure a better return. AgriCool, an affordable IoT-based cold storage controller is designed to address the challenges faced by the farmers in Bangladesh. AgriCool integrates IoT-enabled sensors with a standard split air conditioner (AC) to monitor and control temperature, humidity, in real-time, accessible via a mobile application (Android application). The system leverages a Wi-Fi-enabled microcontroller, digital temperature sensors, and a relay-driven heater mechanism to maintain optimal storage conditions while preventing ice accumulation on AC fins. AgriCool’s simple design with flawless algorithm, enhanced with display and android application ensures easy operation and consistent temperature control. Field testing of the system in Bangladesh revealed that AgriCool can sustain stable temperatures ranging from -2 to +15oC, improving the shelf-life of perishable goods. At an estimated cost of USD 290, this affordable cold room controller system could offer substantial benefits for farmers, providing reliable cold storage and flexibility to store fruits and vegetables for better market conditions and thus preventing post-harvest loss and ensuring food security.
