Sudoku 21: Thermo Sudoku

I wish a very happy birthday to Pranav Kamesh. In the Indian sudoku & puzzling community, this name needs no introduction. At such a young age Pranav has attained so many feats. On a personal level, Pranav is the closest to me among the 5 champs who had started sudokuing with me. If you like a sudoku on this blog, you should thank Pranav as well. More than 60% of the sudokus till date have been tested by Pranav.

Here is a Thermo Sudoku with Pranav's initials as a theme.

Rules: Classic Sudoku rules apply. Additionally the digits in the thermometer shapes must be strictly increasing in each cell from the round bulb to the flat end.
