If you fancy yourself a budding meteorologist, OpenSignal's latest app release might just be the resource you've been waiting for. WeatherSignal turns your Android phone into a mobile weather station by tapping into sensors you didn't know your phone had in order to measure local atmospheric readings. With your consent, the app then submits this data to a collaboratively updated weather map for the world to share. Those of you who have used OpenSignal's previous app to find the best local WiFi connections might recognize the concept behind the company's latest initiative.
WeatherSignal is capable of measuring temperature, humidity, pressure, light, magnetic flux, and acceleration.
