The invention relates to a movable barrier operator with a microelectromechanical positioning sensor, or a movable barrier operator that employs an inertial measuring unit to receive a signal associated with a barrier position, and communicate that signal to one or more devices. A device in communication with the movable barrier operator may be enabled for receiving information pertaining to the barrier and for providing commands that actuate the barrier at precise barrier parameters. In an exemplary embodiment, a movable barrier such as a swing-arm gate may be accurately controlled without requiring manual positioning mechanisms, or otherwise require physical components to set the gate's open and closed limits. Additionally, accurate information may be communicated to a user device, for monitoring and providing maintenance to the movable barrier system.
