| Abstract: | Aimed at the problem of measurement errors caused by the interference of temperature and humidity sensors in the same measuring system, a data processing model based on the quadric surface fitting theory is proposed. In the experiment, taking the integrated temperature and humidity sensor for example, multi temperature and humidity are calibrated by the sensor calibration system and these data are processed based on the quadric surface fitting equation. Experiment results show that this method improves the measurement accuracy of temperature and humidity sensors and has a high practical value. |
