If you ever need to know if your garage door is open or closed, the Seco-Larm SM-226LQ is an excellent choice.  This sensor provides a contact closure output, making it easy to integrate into many of the IoT controllers we manufacture.  Use this sensor to detect the open/closed status of overhead garage doors.  This magnetic door sensor features a large operation gap (2 3/4″) and a heavy duty build.  This sensor was designed to mount on your garage floor, and provides a closed switch output when the door is closed.  The switch opens when the door opens.  This door sensor is rugged, simple to set up, and reliable for daily use.
