To provide a sensor module capable of acquiring a log of sensor data under transportation or the like.

The sensor module comprises a sensor 101, an A/D converter 110 for converting analog detected values S1 of the sensor 101 into digital detected values S2, a memory 130 for accumulation for accumulating the digital detected values S2, an interface section 140, and a control section 120 for outputting the plurality of digital detected values S2 accumulated in the memory 130 for accumulation to the outside from the interface section 140 in response to a trigger signal T. Since the acquired digital detected values S2 are fed to the outside as a whole, it can be used for acquiring data log under transportation. Since the acquired digital detected values S2 are stored in the memory 130 for accumulation as they are, power consumption of the sensor module can be reduced.
