Abstract
A sensor unit includes: a substrate; a first sensor module that is disposed at the substrate and that includes a first acceleration sensor; and a second sensor module that is disposed at the substrate and includes a second acceleration sensor, in which the first sensor module and the second sensor module are arranged to be adjacent to each other at one surface side of the substrate, the first acceleration sensor is eccentrically disposed at the second sensor module side in the first sensor module, and the second acceleration sensor is eccentrically disposed at the first sensor module side in the second sensor module.
Claims8
A sensor unit comprising:
- a substrate having a first surface parallel to a first direction and a second direction intersecting the first direction;
- a first sensor module disposed on the first surface of the substrate and including one or a plurality of acceleration sensors;
- a second sensor module disposed on the first surface of the substrate and including one or a plurality of acceleration sensors;
- and
- a third sensor module disposed on a second surface of the substrate opposite to the first surface and including one or a plurality of acceleration sensors, wherein
- the first sensor module and the second sensor module are arranged adjacent to each other on the first surface of the substrate such that the first sensor module and the second sensor module are arranged side by side along the first direction,
- all of the one or the plurality of acceleration sensors included in the first sensor module are positionally biased toward a second sensor module side within the first sensor module when viewed from a direction perpendicular to the first surface of the substrate such that the one or the plurality of acceleration sensors included in the first sensor module are located closer to the second sensor module than a virtual line that intersects a center of the first sensor module and extends in the second direction,
- all of the one or the plurality of acceleration sensors included in the second sensor module are positionally biased toward a first sensor module side within the second sensor module when viewed from the direction perpendicular to the first surface of the substrate such that the one or the plurality of acceleration sensors included in the second sensor module are located closer to the first sensor module than a virtual line that intersects a center of the second sensor module and extends in the second direction, and such that the one or the plurality of acceleration sensors included in the first sensor module and the one or the plurality of acceleration sensors included in the second sensor module are arranged close to each other,
- the third sensor module is arranged to overlap the first sensor module when viewed from the direction perpendicular to the first surface of the substrate, and
- all of the one or the plurality of acceleration sensors included in the third sensor module are positionally biased toward the second sensor module side within the third sensor module when viewed from the direction perpendicular to the first surface of the substrate.
