MULTIVARIATE DETECTION DEVICE AND MULTIVARIATE DETECTION METHOD

摘要

Disclosed is a multivariate detection device provided with a detection unit (1) for detecting a plurality of physical variates related to physical phenomena including sound, static pressure fluctuation, dynamic pressure fluctuation, acceleration, light irradiation change, and temperature change, and a determination means (3) for determining the kind of the physical variate on the basis of an output signal outputted from the detection unit (1), the detection unit (1) being configured by a silicon microphone (5). The silicon microphone functions as a complement metal oxide semiconductor (CMOS) and electronically detects light. A condenser lens (13) is provided in a casing for housing the silicon microphone. Consequently, a chamber becomes unnecessary by using the silicon microphone instead of a capacitor microphone, and thus light can be directly detected.
