Arduino choice and parts

Hi my name is Giowainy and im building a heated platform.
It has come to my attention that the Arduino would be perfect to control the tempature.
I heat my platform with 5 elements and i want to set a specific tempature for my platform, but I just don't know which arduino or attatchment would be best to buy to be able to program it.

Can anyone please help me?

Please provide more information on this heated platform and the elements.

Is this for a 3D printer?

Did you buy the platform or are you building it? If you bought it then post a link to where you bought it from. Use the chain links icon on the toolbar to make the link clickable.

Is there any type of a temperature sensor built in?
