I heard that a barometer sensor is inatalled in the flight to mesure the altitude from the surface.
I used a program converting txt log file to cvs format like healthy drones.com.
How can I get a barometer value with flight log file.
Actually, we will try to observe the atmospheric components vertically such as, temperature, humidity, and air pressure with the Phantom 4.
Temperature and humidity sensors will be hung 10m under the flight body.
Unfortunately, we don't have any air pressure sensor. So we think the barometer data from Phantom 4 may be usefull to analyse air pressure data.
Because we will set a ground-based weather observation that gets air pressure data at ground level.
TIA.

Hi , i have recently found that feature of my P4 and it shows the air presure in bars. Although i am not sure how correct it is. Do you have it setup on your , have you any idea how accurate is it?

Interested to hear that you are doing this. i am about to embark upon the same sort of adventure, recording temperature profiles up to 400ft. I am particularly interested in doing them with inversions and sea breeze fronts. using a tinytag myself. Please do keep us up to date on progress.
