Wireless technologies for distributed sensor networks used in measurement and automation systems

In this paper we present the modern wireless technologies for realization of distributed measurement and automation systems. The new radio transmission technologies and protocols like Wi-Fi, ZigBee, Bluetooth offer facile way for connections between sensors and devices from a complex measurement system. The first part of the paper contains a general overview of these techniques, making a comparatively analysis of their performances and facilities, useful in the design and implementation of measurement systems. In the last part of the paper we present an application for temperature measurement and monitoring with ZigBee communication. The measurement system was implemented with MegaAVR development board.
