Abstract: In some examples, a sensor device is to mount to a barrier pivotable between an open position and a closed position, the barrier being on a moveable platform. The sensor device includes an accelerometer to measure acceleration data and a rotation sensor to measure rotation about an axis. The sensor device includes at least one processor configured to determine an open/close status of the barrier based on the acceleration data and the rotation data, and an orientation of the moveable platform.
