The newly released Galaxy S4 device, already famous by now, is the only device currently on the market that has an inside ambient temperature and humidity sensor. This is really great as you can install apps and measure the temperature on the spot, as online weather widgets that use weather forecasts are not really the most accurate thing.
Weather Station App
This app uses all 3 Galaxy S4 sensors: thermometer, barometer and hygrometers hows you the computed info (temperature, pressure and dew point) on a nicely designed app. You can enter the app directly to read the stats or you can use the on screen widgets. Among the features of the app there are notification alerts for when the temperature reaches a pre-determined value, indicators for rising/falling/steady readings, graphic representations of the data, screenshot share option and more.
Here are some screenshots with the app:
You can download Weather Station app from Google Play
. As I said, it will only work for Galaxy S4 as other devices don't have the sensors yet.
