| 摘要 |
The present invention includes a first substrate having a sensor part for measuring a measured factor and a second substrate that is to be detachably stacked on a lower side of the first substrate, the second substrate including: a signal processing part that processes a measurement signal obtained by measurement by the sensor part; a power supply part for feeding power to the sensor part; and at least either a memory that stores measurement data obtained by being processed in the signal processing part or a communication part for transmitting the measurement data by wireless, wherein the second substrate is in common use for a plurality of kinds of first substrates different in measured factor measured by the sensor part from each other. |
