If you're a total weather junkie like me, then check out the cool new Netatmo. This innovative personal weather station monitors and tracks the weather and air quality indoors and out and relays this data in realtime directly to your iPhone or iPad along with notifications. The sensors detect current temperature, humidity, barometric pressure, indoor CO2 concentration, and even sound levels (noise pollution). With a simple glance at your iPhone or iPad, you can see current conditions or view detailed graphs and charts using the historical data it's collected to detect patterns and cycles. You can even connect additional sensor stations around your home to the same account. Check out the video below to see it in action.
