Air pressure sensor with temperature compensation
An air pressure sensor that has a first conductive membrane configured for deflection in response to pressure differences between air at a reference pressure and air at a pressure to be sensed. The sensor also has a second conductive membrane configured for deflection in response to a change in temp...

| description | An air pressure sensor that has a first conductive membrane configured for deflection in response to pressure differences between air at a reference pressure and air at a pressure to be sensed. The sensor also has a second conductive membrane configured for deflection in response to a change in temperature to which the pressure sensor is exposed. The sensor uses a circuit in electrical communication with the first and second conductive membranes, that obtains a first signal and second signal from the first and second conductive membranes respectively. The first and second signals are indicative of the deflection of the first and second conductive membranes. The circuit adjusts the first signal by the second signal to generate an output signal indicative of the air pressure. |
