Claim Text:
1. A sensor module characterized by comprising: a first detection element that detects acceleration from outside; an acceleration signal processing unit that processes an acceleration signal detected by the first detection element; a first filter that removes a noise from the signal processed by the acceleration signal processing unit; a second detection element that detects another physical quantity than acceleration; a first physical quantity signal processing unit that processes a physical quantity signal detected by the second detection element; a second filter that removes a noise from the signal processed by the first physical quantity signal processing unit; a signal component analysis unit that analyzes a frequency component of the signal processed by the acceleration signal processing unit, determines whether or not a physical quantity corresponding to a frequency split component representing a difference between a frequency in a drive direction of the second detection element and a frequency in a detection direction of the second detection element is applied, and, if determining that the physical quantity corresponding to the frequency split component is applied, outputs an output stop signal; a first output control unit that stops output of the signal output from the first filter when the output stop signal is output from the signal component analysis unit; and a second output control unit that stops output of the signal output from the second filter when the output stop signal is output from the signal component analysis unit.
