compilation terminated. exit status 1 error compiling for board arduino/genuino uno
Two errors I see is a typo and missing semicolons.

const int ledPin=13
int piesoPin=9


Should be

const int ledPin=13;
int piezoPin=9;


Also I see a unnecessary { and } but this cannot cause a compilation error.

Check the delays, when the temperature is higher than 26 degrees you have more delay than when not, maybe this is intended, maybe not.

However, you probably typed over the code, so maybe there are more errors, please add the exact error text and line in your question.
