Abstract
Disclosed herein are methods and systems for detecting the accumulation of dust in a filter of a HVAC system. In one example, there is provided a capacitive sensor system. The capacitive sensor system comprises a first conductive mesh(120), a second conductive mesh(130), a first filter media (110) disposed between the first conductive mesh(120) and the second conductive mesh(130), and a circuit configured to measure a capacitance of a first capacitive sensor formed by the first conductive mesh(120), second conductive mesh(130), and the first filter media(110).
