Abstract: A portable ambient air quality monitor having an enclosure to enclose and protect the monitor from an ambient environment and an airflow intake for controllably allowing ambient air to enter the monitor. A photodiode is disposed at a location downstream from a fan. The airflow from the fan is laminarized by a mesh or baffle to allow a thin stream of air to flow over the photodiode. A sensing region is defined by an intersection of an airflow sampling path and an optical path. The sensing region is also disposed above the photodiode. The airflow sampling path is configured to receive laminar airflow from the airflow intake and for directing the laminar airflow into the sensing region. A light beam is generated from a laser to reflect the light beam for reducing the required area of the sensing region to detect and measure the particles floating in the ambient air.

Abstract: A portable environment quality monitor having an enclosure to enclose and protect the monitor from an environment and for attaching to a user's clothing or jewelry. The enclosure includes a controlled airflow intake for receiving air from the environment in which the monitor is worn for forming an airflow sampling path and for laminarizing the airflow in the sampling path. A sensor, having a sensing region that directs the laminar airflow into the sensing region. A processor is connected to a light scattering aerosol spectrometer (LSAS) that is configured to receive, process and translate photodiode current peaks into particle counts and sizes detected in the air. The processor is also coupled to a memory for storing data corresponding to the particle counts and sizes detected in the environment. The processor further includes an interface to communicate with a host for allowing a user to monitor and track environment conditions.
