Research and application of Outdoor parking detection system based on WSN

摘要

In order to solve inefficient management and inaccurate hand-timing issues of outdoor parking system, the thesis designs a outdoor parking detection system based on WSN. The system consists of parking terminal node, relay node and master node, the parking terminal node mainly uses STM8L SCM with the geomagnetic sensor and the 433MHz wireless transceiver module. By wireless communication protocol and low-power design, the system realizes wireless data collection, locating parking space information and automatic timing. Test results show that the system possesses low-power, high-performance benefits, and can actually be applied to outdoor parking spaces detection.
