Barometer reading issue

Hello,

I started to test the barometer and the readings are unstable. I installed the real time kernel for RPi 1 and run the Barometer example provided in Docs section. I did the test inside and here is what I got:

pi@raspberrypi ~/Navio/C++/Examples/Barometer $ sudo ./Barometer
Temperature(C): 25.924917 Pressure(millibar): 1007.512451
Temperature(C): 25.882750 Pressure(millibar): 1007.472473
Temperature(C): 25.893848 Pressure(millibar): 1007.498840

Temperature(C): 25.915644 Pressure(millibar): 1007.522278
Temperature(C): 25.925255 Pressure(millibar): 1007.510132
Temperature(C): 25.923901 Pressure(millibar): 1007.525696
Temperature(C): 25.929453 Pressure(millibar): 1007.519531
Temperature(C): 25.932972 Pressure(millibar): 1007.468018
Temperature(C): 25.936966 Pressure(millibar): 1007.479919

I read that it could be linked to power supply so I tried two different power sources (usb and power module) but it gave the same results.

Any idea of what could be wrong?
