Design of Chaohu Water Quality Monitoring System Based on ZigBee Technology

In order to solve the problems of poor real-time performance, low efficiency and high cost of traditional water quality monitoring methods in Chaohu, a water quality monitoring system is designed based on ZigBee technology. Firstly, the paper analyzes the important factors of current water pollution in Chaohu; the characteristics of water quality, such as pH value, temperature and dissolved oxygen are established, and the overall structure of the monitoring system is given. Secondly, according to the characteristics of the parameters, the corresponding signal conditioning circuit is designed, and the formula for calculating the characteristic parameters is derived.Finally, according to the function of various nodes, the software flow based on the ZigBee protocol stack is designed,and the experiment is carried out by means of the way of carrying the nodes. The experimental results show that the method of wireless sensor network has low cost and high reliability, and can meet the application requirements of#br# water quality monitoring.#br#
