WeatherSignal Turns Your Smartphone Into A Super-Sensor

Almost all of us have used a weather app on our smartphones at some point. They’re very common and come pre-installed in many smartphones these days. Trouble is you need to have an internet connection to be able to update them. But what if your smartphone could become a weather forecasting station? That would obviously be much more convenient. And that’s exactly what an app WeatherSignal is trying to accomplish. It harnesses the power of all the sensors available on modern smartphones, and in turn produces different readings that simply aren’t possible with normal smartphone hardware.

The WeatherSignal’s basic operation comes from battery temperature readings. The app designers looked for connections between ambient temperatures and battery temperatures, and surprisingly, they found some correlation between the two. After that, it was a matter of gathering lots of readings to see if the correlation existed for all the cases. And certainly enough, there were some patterns that repeated. That’s how WeatherSignal originated.

The developers have released the app on the Play Store. By doing this, they’re going to get access to hundreds of millions of readings from accross user’s devices. That’s how their original prediction formula is going to be finely tuned, to give more accurately readings. And don’t worry, they’ve already ironed out kinks like what if the battery temperature is being influenced by clothing, friction and so on. All they need now is some help from the public. The more readings they have, the more precisely they can tune their app.

Besides the temperature, the app is uptil now able to give our lux readings for the amount of light around the smartphone. Other interesting readings like pressure, humidity(Samsung Galaxy S4 only), magnetic flux and acceleration are also part of the package. If you’ve got an Android smartphone, give this app a try. You’ll be witnessing an interesting scientific experiment in action and helping the designers gather valubale data as well.
