Need a way to send 5 to 6 measurements wirelessly from sensor on a phone

I have this science fair project in which I have to make a car which can detect gases, smoke, has a camera, and has a very good wireless range...URGENT

You have a project, but you haven’t told us what you have down

How is this urgent?

Well, good luck with that I'd say! It sounds like you have your work cut out for you.

By the way, Arduinos can't do much with cameras, and basically nothing with video data.

Wow! Very impressive.
