| Summary: | Applications that involve monitoring of water quality
parameters require measuring devices to be placed at different
geographical locations but are controlled centrally at a remote
site. The measuring devices in such applications need to be small,
consume low power, and must be capable of local processing tasks
facilitating the mobility to span the measuring area in a vast geographic
area. This paper presents the design of a generalized, low-cost,
reconfigurable, reprogrammable smart sensor node
using a ZigBee with a Field-Programmable Gate Array (FPGA)
that embeds all processing and communication functionalities
based on the IEEE 1451 family of standards. Design of the sensor
nodes includes processing and transducer control functionalities
in a single core increasing the speedup of processing power due to
interprocess communication taking place within the chip itself.
Results obtained by measuring the pH value and temperature
of water samples verify the performance of the proposed sensor
node. |
