Temperature (in Degree) = ( raw temperature output / 340) + offset

Where, offset = 35 + (521/340) = 36.5323

Thanks for your formula. I'll try later at home. Is 521 on offset formula right or it's -521?

Sorry for late reply. Offset is correct 36.5323. So your final equation is

Temperature = (raw output/340) + 36.5323.

Here when you put raw output = -521 you will get temperature = 35 degree

Let me know how accurate is temperature sensor of MPU.
