【摘要】 型号为MLX90614的传感器是红外测温传感器中的一种，常作为测量体温设备的核心部件。在应用此传感器测温的时候，测得的体温值存在误差，需要对该传感器测温进行校准处理。设计了一款基于STM32F103ZET6芯片的测温校准实验设备，包括红外测温模块、 OLED显示屏模块、按键模块和DS18b20测温模块等模块。根据协方差公式，结合实际的使用场景，提出了一种测温校准模型，以提高测温的准确性。更多还原

【Abstract】 MLX90614 is a kind of infrared temperature sensor, which is often used as the core part of temperature measurement equipment. When the temperature is measured by this sensor,the temperature value measured has errors, so it is necessary to calibrate the temperature of this sensor. A temperature measurement calibration experimental device based on STM21 F1032 ET6 chip is designed, including infrared temperature measurement module, OLED display module, button module, DS18 b20 temperature measurement module and other modules.According to the covariance formula and actual use scenarios, a temperature measurement calibration model is proposed to improve the accuracy of temperature measurement.更多还原
