About Wireless Sensor Network Kit ( Scientech 2311W v2.0 V):

 

Wireless Sensor Network (WSN) research has enabled large scale monitoring using small Sensors with radio links. The technological advance in wireless communications and microelectronics has enabled the development of small, low-cost Sensor Nodes. Wireless Sensor Networks are developed to organize and control these Sensor Nodes, which have sensing, data processing, communication and control capabilities. Information collected from these Sensor Nodes is routed to a sink Node via wireless communication approach. The research in the Wireless Sensor Network has focused primarily on the networks issues such as routing, data dissemination and aggregation of co-related data for downstream data delivery. The combination of small size, low cost and wireless networking functionality makes Wireless Sensor Network (WSN) technology exceptionally scalable.

Scientech 2311W v2.0 Wireless Sensor Network will help users to design their own WSN network and also help them to understand the overall concept & its applications.

Sensor Lab (Scientech 2311):


Scientech TechBooks are compact and user friendly learning platforms to provide a modern, portable, comprehensive and practical way to learn Technology. Each TechBook is provided with detailed Multimedia learning material which covers basic theory, step by step procedure to conduct the experiment and other useful information. Scientech 2311 Sensor Lab comprises of sensors and transducers which provide the fundamental knowledge of sensing light, pressure, temperature, IR and many more non electrical entities. Since, most of the sensors give signal which show small variation and are of low level output, these signals need to be converted into a form that is measurable and could be used efficiently. The lab consists of various signal conditioning blocks which perform amplification, filtration, signal conditioning and all the required operations which are acceptable to the input devices. 7″ capacitive touch screen LCD is inbuilt for output device with easy to use instructions and graphical user interface, to display waveforms, to plot characteristics with the help of graphs, for reading operating manual and watching tutorials. Sensor Lab is a standalone TechBook. It does not require external Oscilloscope for measuring, or observing the output and characteristics of the sensors interfaced.
