Abstract

A simple sensor for measuring the air density in the atmospheric pressure has been developed using a usual optical fiber cable and a radioactive alpha-ray sour. The air density wuld be measured with an accuracy of ±4x10^-6g/cm³ in the range from 1.07 X 10^-3g/cm³ to 1.309 X10^-3 g/cm³. Coupling the two air density sensors has also developed the absolute humidity sensor.
