Design and Implementation of ZigBee-Based Multi-Sensor IoT Wireless Monitoring System

With the rapid progress of urban transport construction across the country, the overall number of traffic signals has increased dramatically. Signal failures due to imperfect signal system construction and inadequate operation and maintenance management also occur from time to time. This paper introduces the principles and application features of Zig Bee wireless communication technology and discusses the design and implementation of a traffic signal O&M system based on this technology to aid fault monitoring and traffic accident prevention.
