Topo map showing a pass over a hill at 850 feet

Altimeter graph on the M5 Stack Cardputer, sowing an altitude spike of 582.2 feet

Think speak plot, showing the inverse relationship between barometric pressure and altitude

Altimeter accuracy confirmed. topo map gives this pass at 580 feet, altimeter logged it at 582.5.

It runs and plots this formula, flashed via #Arduino_IDE :

h = 44330 * [1 - (P/P₀)^(1/5.255)]

Altitude also plotted on #ThingSpeak, using phones hotspot.

Ok, #M5STACK, now you're just showing off, lol.

Pretty sweet little altimeter for less that $35.
