a problem about barometric pressure sensor(MS5611-01BA03)

Hao Zhang
hi everyone

i tested my quadrocopter(Lisa/M 2.0) in the AP_MODE_ATTITUDE_Z_HOLD mode.
but it could not hold attitude stably.
i think it is problem in the barometric pressure sensor(MS5611-01BA03) perhaps.
so i observed baro raw value via paparazzi center.
please look at below picture.

the baro_raw_abs value is abnormal,right?
i want to know where is the problem, and how to solve it?

look forward to your favourable reply.
thank you very much!!

Dear Hao Zhang,
i think the data is normal.

Please isolate the holes of the sensor with same floam (1-2cm).
This will damp turbulences.
