  • Hello Sparkfun folks,

    Working on building an altimeter that collects the highest reading and displays it on a seven segment display for students in a middle school science class who are building soda bottle rockets. I've got pretty much everything going well but when I got this set up with the example Altimeter code provided by Sparkfun I'm getting some off readings. My temperature is actually close to perfect (reading 63.5 F which is only 1 degree off from my thermometer in my room) but my altitude is reading in a range from -120 to -70 without me moving the sensor at all. My actual altitude is around 400.

    Any suggestions as to what might be going on? I've heard some people say I should run some sort of calibration code but I can't seem to find an example of that and I don't think I could write that myself.

    Thanks!

No public wish lists :(
