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.
