IOT Based Smart Maize Crop Storage System by monitoring real time environmental parameters

Abstract: The agricultural sector in KAMONYI District, Rwanda, faces significant post-harvest losses, particularly in maize storage, due to inadequate monitoring and management of storage conditions. This project aims to develop and implement an intelligent maize crop storage system using the Blynk cloud platform to ad- dress these challenges. The system utilizes NodeMcu, DHT11 sensors and gas detectors to monitor crucial storage parameters such as temperature, humidity, CO2 levels and Light detector. During our research, we visited a store called Rumbuka Seeds in Kamonyi District, where the current system fills maize into slots. To enhance this system, we propose adding DHT11 sensors, LDR sensor and MQ2 and different actuators like lamp, heater and fan in order to maintain optimal storage conditions. Additionally, the system will be integrated with Blynk to monitor and control the collected data, enabling more effective management of storage conditions. NodeMcu, a microcontroller with Wi-Fi capability, serves as the core unit, collecting data from sensors. These data are then transmitted to the Blynk cloud server, where they are processed and stored in real-time. Farmers can access this data through a user-friendly mobile interface provided by the Blynk application. This interface allows them to view real-time data, analyze historical trends, and receive alerts, facilitating timely interventions without needing to be physically present at the storage site. By continuously monitoring storage conditions and offering actionable insights, the smart maize storage system seeks to reduce spoilage and post-harvest losses, promote sustainable storage practices, and ulti- mately enhance the productivity and profitability of maize farming in Kamonyi District. The inclusion of alert systems within the Blynk app ensures that farmers are promptly informed of any adverse conditions, allowing for swift corrective actions. This innovative approach leverages IoT technology and the Blynk cloud to provide a more efficient and reliable maize storage solution, addressing a critical need in the re- gion's agricultural sector.
