Abstract: ABSTRACT Title: A HARDWARE-BASED PREDICTIVE AIR FILTER PERFORMANCE MONITORING SYSTEM FOR HVAC UNIT A hardware-implemented, power-efficient, and real-time air filter health monitoring system for HVAC (Heating, Ventilation, and Air Conditioning) unit is disclosed. The system integrates an IoT-enabled sensing unit and a machine learning (ML) model implemented on system-on-chipFPGA platform. The sensing unit gathers real-time data on temperature, humidity, and differential air pressure. These are wirelessly transmitted to the detection unit, where a multiclass support vector machine (SVM) classifier, embedded in FPGA logic, predicts the filter condition. The system enables highly accurate (98.78%) filter status detection while maintaining ultra-low power operation and minimal hardware footprint. The invention enables modular, scalable, and edge-deployable HVAC maintenance technology.
