Classification: CPC G | IPC G

Claim 14:
15. A method of measuring a real time particle count exposure of a user comprising:
attaching a personal particle counter device housing to a user, the device housing enclosing a battery that is connectable to a battery charger, a light source, a light detector, a power management circuit, an analog circuit connected to the light detector that includes at least one amplifier in communication with the light detector, the at least one amplifier configured to convert signals from the light detector into amplified electrical pulses, and a microcontroller that is programmed to count particles from the user's local environment that are detected passing through the chamber wherein the microcontroller processes a plurality of different particle size channels to generate particle count data for each particle size channel;
actuating an airflow through the device housing from an air intake to an outlet with an air impeller, the airflow passing through a chamber wherein light from the light source passes through the airflow in the chamber such that the light detector detects particles passing through the chamber;
communicating to the user wearing the device housing a real time particle count level being measured by the personal particle counter device housing and experienced by the user.
