This time of year the sun tends to cause interference with my garage door blockage sensors.
I’ve been manually closing my garage as a result, but finally took the time to “fix” it
PVC threaded female end to slip on. Didn’t glue it, but it’s jammed on tight enough. Sensor still works fine when an actual object is in the path.
Put a white painted shroud on it designed for weather stations, air will flow through and it’ll be unaffected by the sun. I just built one for myself this week, now I can finally measure air temp outdoors (not the surface temp of what it’s affixed to)
