Posts Tagged ‘Altitude’

I have switched to the smaller Aduino Nano for use in my kite flight recorder and this has enabled me to squeeze it into a tiny box that makes it look so nice. It even glows blue when it’s processing data which is rather cool. To recap it takes the temperature and pressure and using a bit of crazy maths in the form of the Hypsometric equation and logs the highest and lowest temperature and altitude extremes.

I have noticed a bit of a problem with it and that is for it to accurately plot your correct starting altitude it needs to know the current pressure at sea level in order for the equation to work. However, this really doesn’t bother me too much as it can measure the height gained accurately.

Of course with anything I make my chief tester puts it through its paces out in the field. Click here to see the video of Charlie Chief Tester.
