linux device driver - How to test a pressure sensor on Android? -

-

I have seen the app, but how can I test pressure sensor driver on Android?

Depending on the solution of your sensor, you see changes based on the height of the meter above the sea level Try to put it on your desk and floor, you should show small changes (or go some floor up in your building).

My experience with the pressure sensor is that, it is quite wrong to measure the height in the small resolutions of the gadget.

To read the values ​​of your sensor, you can try to read the original from sysfs, if you have shell access.

However, I can not see a way to get the head hashes while constructing that merge. I just want to head because it's useless - we only care about merge.
