Baro_comp_P6a-Z5c

Experimenting with smartphone barometers to be functional variometers for paragliding. Latest models have air-tight housings which is troublesome for fast relative changes in air-pressure. But there might be solutions to overcome this and use the otherwise good sensor. In this video I compare a Pixel 6a with an older Xperia Z5 Compact, lifting both devices from 0 to 2m and back.
