Abstract
An airborne, gas, or liquid particle sensor with multiple particle sensor blocks in a single particle counter. Each sensor would sample a portion of the incoming airstream, or possibly a separate airstream. The various counters could be used separately or in concert.
Claims30
A personal particle counter apparatus, comprising:
- a power source in a device housing;
- an air intake and outlet fluidly connected to at least one chamber in the device housing;
- at least one light source that passes through the at least one chamber;
- at least one photo-detector within the at least one chamber, the at least one photo-detector configured to detect airborne particulates passing through the beam in air traversing from the air intake to the outlet;
- at least one amplifier in communication with the at least one photo-detector, the at least one amplifier configured to convert signals from the at least one photo-detector into amplified electrical pulses;
- at least one threshold comparator configured to process the amplified electrical pulses from the at least one amplifier and produces at least one output based on any pulse above a threshold pulse height that is a peak voltage of the amplified electrical pulse, the threshold associated with at least one particulate size channel;
- at least one microcontroller configured to process the at least one output from the at least one threshold comparator related to the at least one particulate size channel to count particles that pass through the chamber;
- and at least one output mechanism or storage device configured to communicate with with the at least one microcontroller to perform, at least one of, store and communicate the collected information.
