Abstract
A leveling sensor, a load port including a leveling sensor, and a method of leveling a load port using a load port are disclosed. In an embodiment, a sensor includes an accelerometer configured to detect leveling and vibration of a load port and produce a plurality of data; a plurality of indicator lights configured to display a level measurement and a level direction based on the leveling of the load port; a processor configured to process the data produced by the accelerometer; and a wired connection configured to connect the processor to an external device.
