COMUNICAÇÃO ZIGBEE APLICADA EM UM SISTEMA DE CONTROLE

This paper presents the development of a communication interface between the standards EIA RS- 232 and ZigBee. Wireless systems do not have extra costs of wiring and infrastructure, allow easy relocation and addition of new devices is simple. The RS-232 is used in various applications and the project's goal was to add the standard advantages of ZigBee wireless communication in a system previously using the RS-232. The project was implemented in educational process control systems. A board was developed, containing a ZigBee module and a conversion system for the RS-232 serial signal. The tests showed that the interface does not interfere with the existing system infrastructure, allowed the workstation to be reallocated and still allowed a single station to communicate with more than one system
