In line river monitoring of nitrate concentration by means of a Wireless Sensor Network with energy harvesting

摘要: Abstract Wireless Sensor Networks (WSNs) are highly promising tools in the advanced automation of chemical analysis processes. This work helps to prove how they can take advantage this technology. Two main drawbacks have been addressed order test applicability: availability suitable transducers and energy supply. The development deployment a WSN for continuous in-line monitoring content nitrates real scenario (River Turia, Valencia, Eastern Spain) then presented. In application an ion selective electrode (ISE) transducer harvesting system based on solar panel used. proposed has deployed along certain stretch river, its operation being studied validated. results obtained not only show applicability analytical environments, but also highlight all advantages offered by novel technology, namely: easy deployment, friendly use, fact that great amount data allows new possibilities both spatial temporal species.
