ABSTRACT:
An allergen detector and allergen detection method for sampling the environment where the detector is located and providing an alarm indication when allergen particulates exceed a predetermined level. The invention comprises a housing having a passageway formed therethrough with a fan disposed in the passageway that is responsive to a flow control signal for creating air flow in a first direction through the passageway. At least one filter is disposed in the passageway for removing particulates larger than allergen particulates in air flowing through the passageway in the first direction. An allergen particulate detector is disposed in the passageway downstream of the filter, with respect to air flow in the first direction, for detecting allergen particulates in the air flowing through the passageway and for providing a corresponding detection signal. A controller is disposed in the housing and coupled to the fan and the allergen detector for generating, at periodic time intervals for a predetermined time period, the flow control signal. The controller is responsive to the detection signal for generating an alarm signal when the detection signal reaches a predetermined level indicative of a condition of excessive allergen particulates present in the environment. An alarm disposed in the housing and coupled to the controller receives the alarm signal and provides an indication of the condition of excessive allergen particulates present in the environment.
