That’s great!
Thanks for those suggestions.

I have suggestion for improvement to be more usable, 90 hight-meters difference is not a good precission. Instead of entering a seal level pressure, ask user to enter current elevation and calculate corresponding seal level pressure by iteration. And more ideas are comming: What about to ask the mobile phone browser for its current time by javascript (instead of NTP call), set the system time and use this real time as for calculation of timestamp of each evelation point in the log in SD card…

Sara,
I used a Ravpower 20000 mAh cell phone power bank with a USB outlet.
Thanks for all you do,
Jim

Hi Jim.
That’s great! Thanks for sharing your experience with the sensor.
This seems one of the best sensors to estimate altitude.
Regards,
Sara

Hi.
We had a great time!
We used a portable charger (power bank).
Regards,
Sara

I took it up in an airplane to 8500 feet and it was spot on with the plane’s altimeter. Having an SD card logger will make it really useful.
