Abstract: A new type of heating circuit is proposed to optimize the design performance of the oxygen concentration detection device. The measurement principle of the zirconia sensor is described in detail, and the detection device is developed with a 32-bit MCU as the main control core. The dynamic voltage regulation heating circuit is innovatively designed, and the main control software control process is established. Significant progress has been made in achieving heating stability and accuracy using model predictive control and proportional-integral-derivative control algorithms. According to the design, the actual product is made, and the calibration and experimental verification are carried out. After calibration, the detection device shows high accuracy in detecting oxygen concentrations.
