"基于AT89C51单片机的水质监测系统设计与原理"

Water quality monitoring system based on AT89C51 single-chip design is a critical solution to the prevalent issue of water pollution in society. This system aims to effectively monitor the concentration of free ions and turbidity in water sources, which is crucial for the preservation of water resources. The design revolves around the utilization of the AT89C51 single chip microcontroller for data collection from water sources. Sensors are used to process the collected water samples and generate analog signals, which are then converted into digital signals through an Analog-to-Digital converter (A/D converter). The converted signals are transmitted to the single-chip microcontroller for processing and displayed on a monitor. This system allows for the accurate determination of water turbidity and free ion concentration, enabling the detection of water pollution levels. The document elaborates on the principles, hardware structure, working mechanism, usage, and the design of individual functional circuits of the water quality monitoring system. Key components include the AT89C51 single-chip microcontroller, data acquisition, A/D conversion, free ion concentration, turbidity in water, and sensors. By incorporating this system, effective monitoring and assessment of water quality are achievable, contributing to the mitigation of water pollution.
