i have my GPS set up and it seems to work fine with the tiny GPS coding. The latitude and longitude values are accurate and stable but the altitude data oscillates about 20m in small steps when the unit is stationary? has anyone else had this issue?
i have this module connected up to an arduino uno. 3.3VDC and using pins 4-5 and the example altimeter code.
but i get incorrect readings for the pressure and altitude the temperature seems about right though.
this is the output
Altitude(m):-25.25 Pressure(Pa):262043.00 Temp©:23.75
my current altitude is approximately +40m is there are value i need to change or is my sensor faulty?
No public wish lists :(
