Abstract
This paper describes the implementation of a Universal Communication Node for building automation systems, which interconnect the sensors and actuators using different communication technologies. A simple protocol addressing the various devices in the automation network and a mechanism for the management of the messages exchanged between different devices were implemented. As communicating elements in the building automation network we used two customized boards based on ATmega328 microcontroller. For wire communication we used the technologies RS-232, RS-485, Ethernet and for wireless Bluetooth, Zigbee, nRF24L01, RF12B, WiFi, GSM/GPRS and Infrared.
