I know this topic was mentioned before, but I still have some problems with it.
I can not have a good accuracy in the altitude measurement with the MPL3115A2 sensor.
Some things I did:
- OSR x128;
- Acquisition rate = 2 Hz.
- OFF_H ajust.
In a room, with the same light all the time, I got:
- Variations about ~2,5 meters in 1 minute;
- Variations about ~15 meters in 8 hours;
Note 1: I can acquire the temperature perfectly, without large variations,but the altimeter has rude variations.
Note 2: I know that the sensor can varies because of the atmosferic pressure, but ~2,5 meter in 1 minutes is not normal.
Is it normal? How can I solve this?
