| dc.description.abstract | The article deals with the present state in the development of wireless sensor
networks - (nodes), trends and new challenges in this interesting area. The highest
priority of this smart instrumentation is the best operating ability of sensor nodes with
suitable protocol communication (for instance Zig Bee). New types of smart sensor
nodes with wireless connection bring some advantages and also disadvantages. There
are problems with communication protocols, interaction between different nodes, and
the main problem is the power supply of the sensor instrumentation nodes. The present
applications have the principle of homogenous nets and they include for instance
smart sensors of temperature, moisture, pressure, water quality etc.
Some experience with wireless sensors, Bluetooth and Zig Bee nodes on
communication with PIC microcomputer will be presented; interesting possibilities
of further development will be shown.
The problem is investigated in the framework of the grant project Czech Science
