Abstract: Cost reduction in wireless sensor networks becomes an important requirement to extend their application in fields where a great amount of sensors is needed. Traditional approach to use multichannel analog-to-digital converter and/or analog multiplexers for analog sensors will not give any reduction in price. Moreover, the analog multiplexer introduces additional measuring error. This article describes in details the developed advanced, robust but cost-effective sensor nodes' architectures suitable for further integration in a node-on-chip. Such sensor nodes can work with any analog and quasi-digital sensors and transducers, and its sensing sub-system lets achieve the best metrological performances. A comprehensive comparative study of sensor node's architectures and sensing sub-systems are presented.

 

Keywords: Sensor nodes, Wireless sensor networks, Frequency-to-digital converter, Universal sensors and transducers interface, Node-on-chip
