A ZigBee-based Aquiculture Water Quality Monitoring System

다국어 초록 (Multilingual Abstract)

To overcome the issues of many monitoring measurement points, wide range, complex working environment and difficult link in aquaculture monitoring, a low-cost, low-power real-time ZigBee-based water quality monitoring system is presented. The system collects, transmits, displays, queries the water quality parameters (the temperature, dissolved oxygen concentration, pH value, and water level) and controls the increase oxygen machine. The low-power MSP430F149 and CC2530 RF chip are the core of the system which is constituted with the sensor nodes, routing nodes and coordination nodes. The time synchronization algorithm enables all nodes in the network sleep and wake up synchronously to ensure the reliability of data transmission and reduce power consumption. The test results illustrate that the network packet loss rate is 0.83% when the distance between the two nodes is 80 m, which meets the demands of aquiculture. The system runs stably, measures accurately and can automatically regulate the water quality, has certain market value and wide prospects of application.
