what does capture() returns? #48

Closed wenbozzz closed 3 years ago

it says

Image data from capture() is 12-bit, non-normalized (raw sensor data).

I have a lepton 2.5 dev kit I would assume it should be the temperature value for each pixel but when I put a melting ice cube (arround 0 degree C) and a cup of coffee (tested with probe, arround 55 degree C) in front of the sensor, the minimum in the array is 27415 and maximum value is 32709 with doesn't really make sense to me

The values are actually in centikelvin, which is (K * 100). So if you have a value of 27415, it means that the temperature value is 274.15 Kelvin, which is 1 Celsius.

Oh thank you so much for this. Never would have thought it's kelvin 🤣
