Tilt-up garage door clearance sensor

[Atesz]

Hello,

I have a tilt-up garage door, and I would like to automate it. However since it is a tilt-up door, in order to close/open I need to make sure nobody/nothing in the way.

I have a thought of using ultrasound sensors, infrared sensors. The main question is how to cover the area in which an object can block the door ?

The main concern is the safety. I dont want to hit a child or damage a car which is in the way of the door.

Any ideas are more than welcome.

Thanks in advance

Basically you have 2 options:

1. You are present to watch when the port goes down
2. something expensive like this: https://duckduckgo.com/?q=Safety+Light+Curtains&t=canonical&iar=images&iax=images&ia=images
