PORTABLE DEVICE FOR MONITORING ENVIRONMENTAL CONDITIONS
First Claim
1. A portable environment monitor and tracking system substantially in the vicinity of a user comprising:
- an enclosure to enclose and protect the monitor from an environment, the enclosure having a controlled airflow intake for receiving ambient air, for forming an airflow sampling path and for laminarizing the airflow in the sampling path;
a sensor, having a sensing region, coupled to the airflow intake in the sampling path for receiving laminar airflow from the airflow intake and for directing the laminar airflow into the sensing region to detect and measure particles entrained in the ambient air, the sensing region including a Light Scattering Aerosol Spectrometer (LSAS);
a processor coupled to the sensing region, configured to receive, process and translate data received from the LSAS into particle counts and sizes detected in the ambient air; and
a memory, coupled to the processor, for storing data corresponding to the particle counts and sizes detected in the environment.

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.
