MPL3115a2 readings are not accurate

        I am working on a project where I have to sense the pressure readings on various floors of a building. The hardware I am using is Rapid IoT with MPL3115a2. I am reading the value for every second. But my values are not accurate when I compare it with other barometers. I have tested it multiple times but the values are very random. 


Why is it so? I also checked the product datasheet and NXP websites. It was mentioned, the accuracy is good. But there are a lot of fluctuations in the pressure readings(it feels like a random number readings).


Can you anyone tell me whether rapid iot which has an embedded MPL3115a2 is the right fit?

if not please suggest some other barometric sensors to work with.



Thanks and Regards
