Abstract:
1. 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 a pressure sensor and an acceleration sensor, wherein each of said plurality of physical quantity sensors are 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; 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, said molded body comprising a through-hole extending upwardly from a pressure receiving portion of the pressure sensor and allows fluid communication between the outside of the molded body and the pressure receiving portion; and 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.
