@TechConnectify Now I’m curious about automatic doors. I remember when they had the framed plastic mats to trigger the doors, then slowly most places have changed over to the IR sensors - which i assume work similarly to the alarm motion sensors? I also remember some places had the plastic mats flush to the floor/exterior sidewalk, while others had a clearly raised frame.
@TransitBiker IR sensors you say?:
