Internet of Things
This research develops a multiplatform system for detecting
abnormalities in melon leaves, integrating an Internet of Things (IoT)
approach using Jetson Nano, a Streamlit-based website, and a mobile
application for real-time monitoring. The system employs
preprocessing with Average Histogram Equalization (AVGHEQ) to
enhance image quality, followed by modeling with the YOLOv7
algorithm on a dataset of 469 training images and 52 test images,
validated through 5-fold cross-validation. The model achieved a mean
Average Precision (mAP) of 84% with an inference detection time of 4.5
milliseconds. Implementation on Jetson Nano resulted in a 25% increase
in CPU usage (from 25% to 50%) and a 20% increase in RAM usage
(from 70% to 90%). By combining these platforms and leveraging
robust data preprocessing and modeling techniques, the system
provides an accessible, efficient, and scalable solution for agricultural
monitoring, enabling farmers to address plant health issues promptly
and effectively.
