Sensor for wearables altitude measurement

[Andy__]

Apparently, four pressures are available for new design, BMP581, 390 and the "robustness against water" 585 and 384.

Which is most suitable for cell energy limited, high accuracy wearable application? 

No immersion under water.  Sensor  inside casing (with small 'protected' hole for air flow) and useable with mild rain.  The small-sized non 'robust against water' type is good, right? 

How would you comment on the accuracy of the four sensors?    Many thanks

Hi Andy__,

Thank for your feedback.
We recommend using high accuracy and low-power pressure sensor BMP581 and BMP585.
BMP581 itself does not support waterproofing, and a waterproof breathable membrane needs to be added to the structure.
BMP585 is a waterproof barometer that supports waterproofing.
