Sensor device

A sensor unit comprising:

• a lead having edge portions formed as lead terminals serving as input/output terminals;
• a plurality of physical-quantity sensors including an acceleration sensor and a rotational angular-velocity sensor, each of said plurality of physical quantity sensors disposed relative to said lead;
• a signal-processing circuit disposed relative to said lead and adapted to process a signal from each of said physical-quantity sensors;
• and
• a molded body made of a plastic material, and formed to seal said lead, said physical-quantity sensors and said signal-processing circuit in such a manner as to allow said lead terminals to protrude outside said molded body, wherein said signal-processing circuit is operable, based on the signal from at least one of said plurality of physical-quantity sensors, to control the ON/OFF action of the remaining physical-quantity sensors.

• a plurality of physical-quantity sensors each disposed relative to said lead and adapted to measure a physical quantity;
• a signal-processing circuit disposed relative to said lead and adapted to process a signal from each of said physical-quantity sensors;
• a molded body made of a plastic material, and formed to seal said lead, said physical-quantity sensors and said signal-processing circuit in such a manner as to allow said lead terminals to protrude outside said molded body, wherein said signal-processing circuit is operable, based on the signal from at least one of said plurality of physical-quantity sensors, to control the ON/OFF action of the remaining physical-quantity sensors, and wherein each of said plurality of physical-quantity sensors has substantially the same height dimension;
• and
• said molded body has a portion extending between each of said physical-quantity sensors and an outer surface of said molded body on the side of said physical quantity sensor, and another portion extending between said lead and an outer surface of said molded body on the side of said lead, each of said portions having substantially the same thickness dimension.
