Abstract
A device for measuring a position of a panel of an overhead garage door is described. The device has an accelerometer, an atmospheric pressure sensor, and a processor. The accelerometer is attached to the panel and detects a motion or vibration of the panel. The atmospheric pressure sensor triggers a measurement of an ambient atmospheric pressure in response to the detected motion of the panel. A state of the panel is determined based on a combination of the measured ambient atmospheric pressure and the detected motion of the panel.
