I am developing an android app for my project, I need to find room temperature as part of it. I am using Droid 2 A955 model for testing.
My Questions are:
There is the age old method of letting the phone and a "good" thermometer stabilize at room temperature (a few hours) and read both.
Then put it outside in a nice wintry garage at about 35F let it stabilize. Then pray for linearity.
Empirical is always nice. I am very interested in measuring a constant temperature in an empty house, and watch for the temperature dropping (or rising!!)
