Paper deals with present state in the development of wireless smart sensor networks - (nodes), trends and new challenges from this interesting area. The high priority of this smart instrumentation there is the best operating ability sensor nodes with suitable protocol communication (for instance Zig Bee). New type of smart sensors nodes with wireless connection bring some advantages and also disadvantages. There are problems with communication protocols, interaction between different nodes, and main problems there are the power supply of the sensor instrumentation nodes. To the main advantages of smart instrumentation belong local signal processing with duplex communication, compact devices form, function auto testing and data validation, possibility to connecting to ILAN and wireless ILAN. Some experience with wireless sensors (ZigBee nodes and USB sensors) on communication with PIC microcomputer will be presented and will be shown the interesting possibilities for another development.
