Hand-held multi-parameter water quality recorder

Water resources monitoring has become an important research topic because an unreasonable use of water resources results in the deterioration of water environment and affects the development of human beings and nature. The scheme of the hand-held multi-parameter water quality recorder based on the sensor of the YSI6600 was designed. Through the multi-parameter sensor of the YSI6600, the recorder can detect and analyze the water quality of 17 parameters, such as turbidity, PH value etc. The core controller by using the low-power single-chip MSP430F149 makes the entire system with battery-powered. The use of multi-parameter sensor YSI6600 makes collection of data-processing speed and high precision, small error. The advantages of the recorder are the small size, the low cost, the low consumption, the large-screen LCD display, and easily carrying. It can communicate with the computer by RS232, position water quality data of a water area by circumscribed GPS, and provide a favorable data protection for the water sector and environmental sector by the water quality data. It has been played a significant role in environmental monitoring and water quality monitoring. Comparing with the traditional sampling from the river and instrument in the past, the recorder has greatly improved the efficiency of detection.
