Abstract
A barrier sensor device and associated control device monitor operation of a barrier operator system. The barrier sensor device monitors operation of barrier operators for undesirable amounts of strain without barrier operator force as an input. The barrier sensor device instead detects both motion and tilt of a barrier. By monitoring these two aspects of barrier operation, the barrier sensor device compiles data that can be analyzed by the control device and compared to un-strained or previously compiled barrier operator data to determine whether the barrier operator system is under strain and requires service.
