ABSTRACT:
The present invention relates to the field of the detection, analysis and/or determination of matter or particles suspended in fluid. In one particular form, the present invention relates to smoke detectors, which detect unwanted pyrolysis or combustion of material. In another form, the present invention relates to smoke detectors of the early detection type, and which may be applied to ventilation, air-conditioning or duct monitoring of a particular area. In yet another form, the present invention relates to surveillance monitoring, such as building, fire or security monitoring. In still another form, the present invention relates to environment monitoring, such as monitoring, detection and/or analysis of a fluid, zone, area and/or ambient environment, including commercial and industrial environments.
