摘要：An electronic system which facilitates active signs for car park management systems. There is a light sensitive sensor in each car space allowing a very simple circuit to distinguish whether a group of car spaces is full or has one or more vacant spaces available. There is not necessarily a need for a computer or even a microprocessor to ascertain the vacant or full state of a group of car spaces. This electronic system may directly switch devices accordingly.
