Does anybody know if there are Infrared interrupt sensors which I can use in the driveway?
It is my intention to tricker an alarm or event if someone passes this sensor on the driveway.
I googled, but found a lot, but nothing useable, as far as I can see.

searching for such a beam sensor too, could only find solutions with an esp8266 and normal infared beam sensors

Yes, me too. Had a recent attempt to break into garage. The damage caused will cost more than if they'd just walked in!

Anyone have any ideas please?
