The sensor includes piezoelectric transducers and switches. The piezoelectric transducers have different resonance frequencies. The switches are provided to correspond to the piezoelectric transducers, respectively. Each of the switches outputs an output signal corresponding to a voltage generated by an inverse piezoelectric effect of a corresponding piezoelectric transducer of the piezoelectric transducers. The diagnosis circuit diagnoses, based on a difference in pattern of the output signal, whether vibration has newly occurred in the sensor, and switch an output destination of the output signal of the sensor according to a result of the diagnosis."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Sensor module","description":"According to one embodiment, a sensor module includes a sensor and a diagnosis circuit.
