Hi Tao,

Please take a look at this thread with a similar topic.

Have you considered using the MPL3115A2? It allows direct altitude reading (almost no additional computing needed) over the I²C interface and offers an altitude resolution down to 30 cm (with max oversampling enabled) with a relative accuracy of ±0.1 kPa (±8 m). For more information please refer to the AN4528 and the example code is available here. 

Regards,

Tomas
