Abstract
A pressure sensor is capable of detecting a certain pressure and an atmospheric pressure individually and independently in real time, with miniaturization and light weight. This is attained by providing a pressure sensor comprising a first pressure sensor; and an atmospheric pressure sensor. Each sensor includes a pressure-sensitive element and a circuit for amplifying an output signal from the pressure-sensitive element. The amplifying circuit for the first pressure sensor, and the pressure-sensitive element and the amplifying circuit for the atmospheric pressure sensor are provided on the same chip. The amplifying circuit compensates for nonuniformity in characteristics of the pressure-sensitive element due to temperatures.
