Looking for information on building a infrared sensor.

I am just starting to get into electronics and wanted to start with a simple
project, an active infrared sensor for the driveway. Nothing fancy simply
to activate a relay when the beam is broken, I have read something about
modulating the infrared frequency to account for ambient light and would
like to incorporate that into the project.

Thanks
