Motion Detector Suggestion

I will try different placement for the sensor. I had it in the corner pointing straight ahead down the hall as you suspected, so I will move it to be crosswise.

SmartThings Motion Detector Range? I want to limit range so it can be used as a switch

Great question JD… Every PIR (passive infrared) motion detector has different sensitivities – both range and angle. Most PIRs work by using a multi-fresnel (bumpy?) lens that creates a “moving shadow” effect on the actual sensor target. Movement across the “visible” field of the sensor fades in and out of focus and that affects the brightness of infrared light on the sensor, thus telling it there is motion. It’s too bad that these don’t have a “reverse” mode that would project a visible light out from the sensor area through the lens so that you could see a pattern projected on the walls, ceiling, and floor which would approximate the width-scope of the sensing area. But you can possibly guess the area by looking at the lens and picturing what that light pattern would look like. Note:…
