Abstract :
A design of detection system about dissolved oxygen is proposed based on C8051F020 which is an integrated mixed-signal system-on-chip MCU. It can quickly and accurately detect Dissolved Oxygen (DO) in the water. The software adopts Multi-sensor data fusion and temperature compensation to eliminate the effects of temperature and the sensor itself, enhance the measurement precision. And serial communication of RS232 is used in this system which can sent data to upper PC. The system is of high practicability.
