So just something that’s been on my mind. At my workplace there’s an automatic road barrier that lifts up and down when vehicles arrive. However, it’s not used for a carpark system when people wave their tickets or something. It just goes up and down when a vehicle shows up.

However, it sometimes goes up for when say a pushcart is being rolled over whereas it wouldn’t for a guy pushing a bin.

So tldr, how does an automatic road barrier decide that yes, a vehicle is coming, and therefore opens up?

    Technically speaking it would pick up the men in metal armors, not the wooden horse per se.

    But the barrier would lift for the wooden horse full of men in armor indeed.

      Depends on how high on their horse they are: They might be too far away to trigger the sensor.
