Fever is a common symptom of many infections, e.g., in the ongoing COVID-19 pandemic, keeping monitoring devices such as thermometers in constant demand. Recent technological advancements have made infrared (IR) thermometers the choice for contactless screening of multiple individuals. Yet, even so, the measurement accuracy of such thermometers is affected by many factors including the distance from the volunteers' forehead, impurities (such as sweat), and the location measured on the volunteers' forehead. To overcome these factors, we describe the assembly of an Arduino-based digital IR thermometer with distance correction using the MLX90614 IR thermometer and HC-SR04 ultrasonic sensors. Coupled with some analysis of these factors, we also found ways to programme compensation methods for the final assembled digital IR thermometer to provide more accurate readings and measurements.
发烧是许多感染的常见症状，例如在当前的 COVID-19 大流行期间，不断需要监测设备（如温度计）。最近的技术进步使得红外线（IR）温度计成为非接触式筛查多个人的首选。然而，即使如此，此类温度计的测量精度仍受许多因素的影响，包括与志愿者额头的距离、杂质（如汗水）以及志愿者额头上的测量位置。为了克服这些因素，我们描述了使用 MLX90614 红外线温度计和 HC-SR04 超声波传感器组装一个基于 Arduino 的数字红外线温度计，该温度计具有距离校正功能。结合对这些因素的一些分析，我们还找到了为最终组装的数字红外线温度计编程补偿方法的方法，以提供更准确的读数和测量。
