Abstract
A gaseous-fluid environmental sensor having a gaseous-fluid flow system. The gaseous-fluid flow system, in one construction, includes a blower to move the gaseous fluid from an intake port to an exhaust port via a flow path. The gaseous-fluid environmental sensor further includes a controller coupled to a particle count sensor. The controller determines whether the particle count sensor has a fault based on the particle count sensor not sensing a particle or a cosmic ray in a time period.
