Abstract
An environmental sensor including an inlet and an outlet such that a flow of fluid moves from the inlet to the outlet, a particle detection portion to detect particles in the fluid, and a controller connected to the particle detection portion. The environmental sensor can be in communication with a data acquisition system (e.g., via a wireless access point) to form a particle counting system. Also disclosed are methods of operating the environmental sensor and methods of operating the particle detection system.
