1. A sensor module comprising:
a first sensor device containing a first sensor which is a physical quantity transducer, a first measurement circuit receiving a signal from the first sensor and performing a measurement process, and a first interface circuit outputting first measurement data from the first measurement circuit;
a second sensor device containing a second sensor which is a physical quantity transducer, a second measurement circuit receiving a signal from the second sensor and performing a measurement process, and a second interface circuit outputting second measurement data from the second measurement circuit; and
a microcontroller that receives the first measurement data from the first sensor device and the second measurement data from the second sensor device, wherein
the first sensor device includes a first terminal that is used for input of a synchronization signal which is a signal based on an external synchronization signal, and input or output of communication signals,
the second sensor device includes a second terminal that is used for input of the synchronization signal, and input or output of the communication signals, and
the microcontroller includes a third terminal that is used for input of the synchronization signal, and input or output of the communication signals, wherein
the first sensor device, the second sensor device, and the microcontroller receive the synchronization signal and the communication signals as inputs using the first terminal, the second terminal, and the third terminal, respectively, and output the communication signals using the first terminal, the second terminal, and the third terminal, respectively, wherein
the first terminal, the second terminal, and the third terminal are communicatively coupled.
