Very soon your smartphone battery will act as a source of predicting weather condition of your city (or nearby place).
A team of smartphone App developers (Android Apps Developer) and Weather expert is working together on a project that use the temperature sensors built into smartphone batteries to crowdsource weather information.
Latest smartphone batteries have a temperature sensor that usually prevents smartphones from overheating, but the researchers discovered the battery temperatures tell a story about the environment around them.
Crowdsourcing hundreds of thousands of smartphone temperature readings from phones running the popular OpenSignal Android app, the team estimated daily average temperatures for eight major cities around the world. After calibration, the team calculated air temperatures within an average of 1.5 degrees Celsius (2.7 degrees Fahrenheit) of the actual value, which should improve as more users join the system.
James Robinson, co-founder of London-based app developer OpenSignal that discovered the method said,
“The ultimate end is to be able to do things we’ve never been able to do before in meteorology and give those really short-term and localized predictions. In London you can go from bright and sunny to cloudy in just a matter of minutes. We’d hope someone would be able to decide when to leave their office to get the best weather for their lunch break.”
