COMPOSITE SENSOR

A composite sensor includes a first shield pattern that functions as a noise shield of a circuit board, a second shield pattern that functions as a noise shield of a first sensor, and a third shield pattern that functions as a noise shield of a second sensor. The first shield pattern has an impedanc...

Beschreibung
Zusammenfassung:	A composite sensor includes a first shield pattern that functions as a noise shield of a circuit board, a second shield pattern that functions as a noise shield of a first sensor, and a third shield pattern that functions as a noise shield of a second sensor. The first shield pattern has an impedance lower than the second shield pattern and the third shield pattern. The second shield pattern and the third shield pattern are electrically connected to each other through the first shield pattern. Accordingly, deterioration of detection accuracy caused by electrical noise is restricted.
