Design for Intelligent Dissolved Oxygen Sensor System Based on CAN Bus and Embedded USB Host Computer

In order to collect dissolved oxygen in aquaculture and implement reliable transmission and storage,the intelligent dissolved-oxygen sensor system based on CAN bus and embedded USB host computer is designed.It can apply CAN bus to aquaculture field environment.By realtime,reliability and flexibility of the CAN bus,it can display the dissolved oxygen content in water environment,and communicate with the PC.The embedded USB host can operate independently from PC,and save the collected data to the USB mobile storage device,extend the system's storage capacity.The system provides reliable data for control of the dissolved oxygen concentratin.It has good application prospects.
