A Smart Multi-parameter Sensor with Online Monitoring for the Aquaculture in China

Abstract

International audiencePH, DO,ORP, EC and water-level are important parameters of the aquaculture monitoring. But the high cost of foreign sensors and high-energy consumption of Chinese sensors make it impossible for wide use in China. This paper uses MCU STM8L152 to realize the ultralow power design. With simple hardware structure design, the cost of the multi-parameter sensor can be reduced .The experiment data of the multi-parameter sensor contrasting with the results obtained by Hach multi-parmeter meter, indicates that the sensor is reliable to monitor the water quality with low cost, high efficiency and good precision
