With increasing elevation and decreasing pressure, amount of effective oxygen in the air descreasing too. On sea level there's about 20,9% of oxygen in the air. This widget will show you a percentage of oxygen in actual elevation, elevation and if you will have Tempe sensor connected, it will show the temperature too (use at your own risk).</p><p></p><p>Widget will show percentage from real maximmum value (for example 1000m = 18.4 = 88% from max) and real value of oxygen (max 20.9 at sea level). If you like, you can check the effective oxygen information on webpage http://www.higherpeak.com/altitudechart.html</p>
