Abstract
A plurality of sensor units are distributed over an area and communicate via a network with a central monitoring unit. The sensor units include sensor arrays that provide them with raw data in response to the presence of selected compounds in the ambient fluid. The raw sensor data is then processed to compute a local profile, which (a) illustrates a change in the compounds in the fluid from their normal state (change detection) , (b) indicates the presence and total concentration of foreign compounds in the fluid (presence detection), or (c) details the composition and concentrations of defined classes or individual species of compounds in the fluid (composition detection). The local profiles from the individual sensor units are then used to compute a spatial and temporal map for the compounds in the fluid. This map can then be used for a variety of purposes including tracking and predicting the flow of compounds through the area, identifying the source of compounds in the area, monitoring abatement, and controlling industrial processes.
