WANG Shi-ming, YU A-long, YANG Wei-wei. Design of large area aquacultural water quality monitoring system based on Zig Bee[J]. 2014, 33(11): 102-105. DOI: 10.13873/J.1000-9787(2014)11-0102-04.
In order to improve level of intelligence of industrial aquaculture
propose water quality monitoring system scheme based on Zig Bee protocol of wireless sensors networks( WSNs). Design water quality parameters value of dissolved oxygen
pH
ammonia sensor transmitter circuits
realize collection
processing of value of dissolved oxygen
pH
temperature and ammonia nitrogen content
and other parameters
and transmit datas through wireless network to terminal node and then through RS—232 serial port to monitoring center. Test shows that the system has advantages of good realtime
small measurement error
which can well meet the demands of aquaculture water quality monitoring.
