Hello, I'm very new to the Arduino world. I would like to develop a project where I can check if an object (let's say a car at low speed) passed through a certain place and at what time. Any idea on what type of sensors to use to do this? Note: IR is not really a good option. Best Regards …

Note: IR is not really a good option.

Why?
