Tilt / Garage Door Sensor-345 MHz
Garage Door Tilt sensor simply mounts on the top of any garage door. With no magnets to align, this is the fastest and most reliable way to protect overhead garage doors. The tilt sensor will activate when the device is approximately at a 45 degree angle. By moving the actual ball sensor up or down you can adjust this angle by a few degrees. Note that this device has a delay of approximately 1 second to eliminate false alarms cause by wind and vibration commonly subjected to a large garage door.
