There are three types of covers: closed, open, and specific. The closed covers ensure that the electronics are dustproof (not waterproof). The open covers have hexagon-shaped openings so that electronics that require cooling can some fresh air. Open covers can also be used when a sensor is necessary. The specific covers are designed so that, for example, a display or a switch can be mounted.
