Hi guys

I want to do a project on parking lot, here is the description:
-when a car enters the parking lot, a sensor will give a signal
-when its a person, nothing will happen, no signal from he sensor

so my question is how do i need for the project, what kind of sensor do i need to use, etc...

thanks in advance.
