1. A building management system, comprising:
a trigger sensor configured to enter a scanning mode based on detecting a triggering event at a first location of an environment;
a detection unit disposed at the first location of the environment, the detection unit comprising:
a particle sensor configured to detect a particle count of a substance proximate to the first location of the environment; and
a detection unit housing configured to enclose at least a portion of the particle sensor,
wherein the detection unit is configured to:
periodically check whether the trigger sensor has entered the scanning mode; and
provide power to the particle sensor in response to determining the trigger sensor has entered the scanning mode;
an HVAC system disposed proximate to the first location of the environment, the HVAC system comprising an air filter configured to filter the substance; and
a server communicatively connected to the detection unit and the HVAC system and configured to activate the air filter.
