electronic barometer can be read automatically by a computer, chart recorder, or other data taking system

Sooner or later the weather hobbyist wants an electronic barometer, the main advantage being that it can be read automatically by a computer, chart recorder, or other data taking system.

Most electronic barometers use some sort of strain gauge transducer to directly convert pressure to voltage and true weather bureau performance can be difficult to achieve with these pressure sensors due to their significant sensitivity to temperature changes.
