Abstract

The design of oxygen content detecting system based on the Nernst equation is introduced.The zirconia oxygen sensor is used

and MSP430 is used as the intelligent control unit.The thermocouple measurement and compensation circuit

the temperature-control circuit and the signal processing circuit are designed.The temperature of the sensor is made constant by using fuzzy control algorithm only

thus the control process is simplified.In this experiment

the temperature of the sensor can be kept in a range of（750±1）℃.The calibration of the system is made

and the oxygen content modified equation has a good linear relationship.
