Long range barrier sensor
I'm looking for a long range (2.5-3 meters) barrier sensor and I can't find something interesting
Maybe you can help me
I need to detect the car position in my garage and turn on a light to not bump the other car.
My idea is to install 3 or 4 sensors on ceiling to detect which car is the first and with a little of intelligence turns on first or second light.
It's not a problem to install reflector on the ground.
The idea is similar to parking build but it can't be applied in my configuration.
Thanks for your help
