Title: SYSTEMS, METHODS, AND DEVICES FOR UTILIZING A DUST SENSOR INDICATOR
Abstract:
Systems, methods, and devices for sensing dust are described herein. One system includes a controller (450) for utilizing a dust sensor (456) comprising a memory (454) and a processor (452) configured to execute executable instructions stored in the memory (454) to sample a plurality of low pulse occupancies of a particle measurement system at a predetermined interval, wherein the plurality of low pulse occupancies produce a number of spikes. The controller (450) can reduce the number of spikes by applying a recursive moving average to the plurality of low pulse occupancies. The controller (450) can display, on a user interface, an air level condition based on the plurality of low pulse occupancies and the recursive moving average.
