Automatic Control & Weight Monitoring of a Vacuum Based Grain Collecting Machine

This paper presents the design and implementation of an automatic control and weight monitoring system for a vacuum-based grain collecting machine. The system allows users to set specific weight limits, automatically stopping collection upon reaching the threshold to prevent overloading and ensure efficiency. By integrating automation, it enhances precision and optimizes grain harvesting, contributing to smart farming advancements. This scalable solution modernizes agricultural practices, improving productivity for farmers. This system stands out by integrating weight-based auto cut-off, IR fullness detection, and SCR-driven suction control into a cost-effective, field-ready setup for precision agriculture.
