Claim Text:
1. A sensor unit, comprising: a rigid board that has a top surface and a bottom surface opposite to the top surface; a sensor providing a measurement axis, the sensor being fixed relative to the top surface of the rigid board so that the sensor is located closer to the top surface of the rigid board than the bottom surface of the rigid board; a processing unit that is electrically connected to the sensor, the processing unit being fixed to the rigid board; a connector electrically connected with the processing unit, the connector being fixed to the bottom surface of the rigid board so that the connector is located closer to the bottom surface of the rigid board than the top surface of the rigid board; and a memory unit which stores calibration information for specifying a direction of the measurement axis, the memory unit being fixed relative to the rigid board, wherein a projection member of the connector is projected toward an outside of the sensor unit from the bottom surface of the rigid board, the projection member is configured with first and second outer surfaces respectively extending in first and second directions that are different from each other and the projection member further including a plurality of connection terminals that are provided in a row along the bottom surface of the rigid board, the first and second outer surfaces of the projection member of the connector configure a reference plane, and the calibration information defines the direction of the measurement axis with respect to the reference plane.
