Abstract
A networked air quality monitoring system. Such a system could provide information beyond the user's local instrument on air quality over a much larger area. This information could be used by a user to make decisions about frequenting particular areas based on the results, or to alert them to changing conditions in the area so that the user might act before local conditions change.
Claims28
An air quality monitoring system comprising:
- at least one air quality monitoring instrument, the air quality monitoring instrument including at least one air quality sensor having a first light source that emits light at a first wavelength and a second light source that emits light at a second wavelength different than the first wavelength, the air quality monitoring instrument being connected to a communication network;
- and
- at least one server in communication with the air quality monitoring instrument, wherein air quality information, including at least one of a current date, a time, and a position, is communicated from the air quality monitoring instrument through the communication network to the server and at least one of air quality information, including date, time, and position information is aggregated by the server to create an aggregate data set of air quality over a geographic area.

A system for monitoring air quality comprising:
- a first sensor in an optical particle counter having a first light source that emits light at a first wavelength wherein a first detector measures scattered light from a plurality of particles within an airflow between an inlet and an outlet of the first sensor;
- a second sensor in the optical particle counter having a second light source that emits light at a second wavelength different from the first wavelength wherein a second detector measures scattered light from a plurality of particles within the airflow received from the outlet of the first sensor;
- and
- a particle counting circuit that generates particle count data form at least one of the first sensor and the second sensor;
- and a processor that generates a data field that is transmitted to an external device with a communication network, the data field including at least particle count data, a time and a date corresponding to the particle count data.
A method of optically counting particles in an airflow with a particle counter comprising:
- counting particles in an airflow passing through a first sensor of an optical particle counter, the first sensor having a first light source that emits light at a first wavelength and a first light detector that generates particle count signals in response to detected scattered light from particles in the airflow;
- counting particles in the airflow received from the first sensor by a second sensor, the second sensor having a second light source that emits light at a second wavelength different from the first wavelength and a second light detector that generates particle count signals in response to detected scattered light from particles in the airflow;
- and
- processing the particle count signals to generate particle count data, the particle count data being processed by a processor to communicate the particle count data to an external device with a communication network.
