IR temp sensor

[astanapane]

Can you display raw register data?
So you can compare result of your calculation with register value. Maybe sensor have some drift issues.

i can display values depends on the temp...yes.

like 14971. When i divide that by 50 it give me 299,42.

Then i seperate the 299 and the 42 as remainder.

The calculation then is : 299 - 273 in order to get the value in Degree C. The problem is that i do not have the right knowledge to divide that by 273,15. But that is ok for me at the moment.
