How to connect the temp sensor to apm?

HI
im to apm 2.6 board but i want to add the simple lm35 sensor to this board.
as i saw on the net some people proposed the fuel tank level example but i didn’t find the enable pin for sonar module, just wanted to know is it really possible to add any other sensor or at least lm 35 to this module?
any advanced help appreciated
regards
