What's an image sensor?

What's the thing that gives a much more clear image? my friend said the image sensor gives it, is it true or not? cause I was planning to buy Nikon D3100 but said it's not good enough and to buy, I'm planning my work to be on models & photo/weddings

my bid is up to 1000$, what camera should I get? thank you!
