Abstract: Recently, with the rapid development of micro electronics technology, wireless communication technology and embedded system, the technology of wireless sensor network (WSN) has been advanced a lot. At the meanwhile, more and more producers and international organizers want to make the mote more intelligent and standard. Sensor Networks being considered as an emerging area of research in recent years has evolved in itself a large potential to counteract the ongoing system. By networking large numbers of tiny sensor motes, it is possible to obtain data about physical phenomena that was difficult or even sometimes impossible to obtain in conventional ways. Automatic multi-stored car parking system is very good substitute for car parking area.
