With the rapid development of automobile industry, city parking has become a major problem. Tight parking spaces is just one aspect, but the key issue is parking, and timely information for drivers parking is opaque, which means that the owner does not know there is free parking in the vicinity. Parking Information has become a destination near the driver's scarcest resource. Real-time intelligent parking guidance system is an effective way to solve this problem, it can maximize limited resources and can significantly reduce parking personnel costs, IOT wireless parking sensor perception is the key equipment to achieve this goal through its You can quickly build a low-cost real-time parking information systems, intelligent parking guidance systems, urban systems, and so push real-time availability of parking spaces. Things perceive wireless parking sensor WL-WPCD-01 using networking technology, whether it is a new or existing parking lot parking lot without wiring, easy completed the rapid deployment of large-scale intelligent upgrade.
