Electromagnetic chip detectors and associated methods of detecting a metallic chip in engine fluid of an engine are provided. The method comprises supplying an electric current to a circuit extending between a first node and a second node to magnetize both a first electrically conductive terminal and a second electrically conductive terminal spaced apart from each other to define a chip-receiving gap therebetween, and detecting a change in resistance across the first node and the second node. The change in resistance is indicative of a capture of the chip by the electromagnetic chip detector. The chip electrically connects the first electrically conductive terminal to the second electrically conductive terminal. The first electrically conductive terminal is electrically connected to the first node. The second electrically conductive terminal is electrically connected to the second node.

A bioaerosol detector is operated in accordance with one or more first inputs. Operating the bioaerosol detector includes filtering pathogens from the air, extracting genetic material from the filtered pathogens, and analyzing the extracted genetic material to identify the filtered pathogens. While operating the bioaerosol detector in accordance with the one or more first inputs, a change is identified in an operating condition for the bioaerosol detector. In response, the bioaerosol detector is operated in accordance with one or more second inputs. At least one input of the one or more second inputs is distinct from a respective input of the one or more first inputs.
