A modular optical particle counter sensor and apparatus are described that consolidates counting functionality on a single main counter board and has expandable functionality through connections to plug-in system boards. The modular optical particle sensor may be directly connected to a manifold with an integrated venturi for better controlling the flow rate of the air stream passing through the apparatus for sampling.

Modular optical particle counter sensor and apparatus

An airborne, gas, or liquid particle sensor with multiple particle sensor blocks in a single particle counter. Each sensor would sample a portion of the incoming airstream, or possibly a separate airstream. The various counters could be used separately or in concert.

Personal air quality monitoring system

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.

Networked air quality monitoring system

An airborne or liquid particle sensor with a number of advanced features is disclosed. The sensor includes an output channel generating an electrical signal for a particle passing through the sensor, where the electrical signal includes information related to the pulse. The information is processed by the sensor to determine a value that indicates a more accurate particle mass for a sample period than the average mass.

An airborne or liquid particle sensor with integrated bootloader. A particle sensor incorporating at least one bootloader for programming or retrieval of program or data in local memory.
