Abstract
Reliability and accuracy of a sensor are secured while adjustment cost of a sensor module is suppressed. A signal component analysis partreceives a signal output from a signal processing partbefore passing through a low-pass filter, analyzes whether or not application of a fragile frequency with respect to a physical quantity is equal to or more than a threshold level, if the application of the fragile frequency is equal to or more than the threshold level, outputs output stop signals to output signal control parts. The output signal control partsreceive control signals output from the signal component analysis part, and outputs an acceleration signal and a physical quantity signal from which noise has been removed by the low-pass filtersthrough the signal processing parts
