The sensor is just a voltage source - you can't "see" voltage, you need some software to read it and display the results - as pressure or altitude - on the screen. (You can't "use" any sensor without some software. In a cellphone or elsewhere. You plug a keyboard into a desktop - and there's software reading the port that the keyboard is connected to.)
Yes, I know that I cannot use it without software, but I want to know if I can use it with some native Android software from my Galaxy A8. I avoid to use any play store app from at least two reasons:
1. There are full of adds. And those adds eats my battery.
2. Lot of them are not efficient and not intuitive .. .except those ones that are made it by serious companies, rarely I saw something good. I know, I might be wrong, but this is my feeling about android apps after few days of app trials.
So, I guess there is no something native on my smartphone that tell me the air pressure, right ?
