Abstract
An air quality monitoring device and system for monitoring multiple streams of air. The present invention includes structural components to separate and/or obtain multiple streams of air and a single optical particle counting (“OPC”) system. The structural components may include a housing for the OPC system and a conduit. The conduit may be a flexible tube or fixed structural channel. The OPC system may include multiple optical detectors and an optical emitter. The optical emitter may be a laser.
Claims28
An particle detection apparatus for detecting and measuring particles entrained in a fluid flowing in a flow direction within a fluid stream, the apparatus comprising:
- a housing comprising a top side, a bottom side, an upstream side, a downstream side, a first distal end, a second distal end, and an elongate shape;
- a plurality of apertures in the housing extending between the upstream and downstream sides of the housing, the plurality of apertures comprising a plurality of inlets and a plurality of outlets;
- a plurality of sensors disposed within the housing;
- and
- a circuit board disposed within the housing, the circuit board comprising circuits for interfacing with all electronic components and the plurality of sensors.
A method of monitoring filter status based on properties of a fluid in a fluid stream, the method comprising:
- providing
- a fluid stream,
- a sensor disposed within the fluid stream,
- measuring properties of the fluid stream at a time (t1);
- determining a t1 filter operational efficiency based on the measured properties at t1;
- repeating the steps above at subsequent points in time (t2, t3 . . . tn) until the filter operational efficiency reaches a predetermined threshold;
- transmitting a threshold notification to a storage device, a cloud computing system, or a display;
- refreshing the filter status based on the threshold notification;
- and
- displaying the refreshed filter status on a display.
