How to test a pressure sensor on Android?

Question

我已经看过这个应用程序，但是如何在Android上测试压力传感器的驱动程序？

Answer 1

Depending on the resolution of your sensor you might see changes depending on the hight of meters above sea level. Try to put it on your desk and the floor, you should see small changes (or go some floors up in your building).

My experience with pressure sensors is, that they are quite inaccurate to measure the hight of the gadget in a small resolution.

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