Feature Papers represent the most advanced research with significant potential for high impact in the field. FeaturePapers are submitted upon individual invitation or recommendation by the scientific editors and undergo peer reviewprior to publication. The Feature Paper can be either an original research article, a substantial novel research study that often involvesseveral techniques or approaches, or a comprehensive review paper with concise and precise updates on the latestprogress in the field that systematically reviews the most exciting advances in scientific literature. This type ofpaper provides an outlook on future directions of research or possible applications. Choice articles are based on recommendations by the scientific editors of MDPI journals from around the world. Editors select a small number of articles recently published in the journal that they believe will be particularlyinteresting to readers, or important in the respective research area. The aim is to provide a snapshot of some of themost exciting work published in the various research areas of the journal. You seem to have javascript disabled.

Front view of prototype displaying the IR sensor and ultrasound sensor in the top half. The bottom half of the device includes the push button switch and battery holder. SR04, push button switch, Arduino Nano board, OLED display SSD1306, and IR temperature sensor MLX90614. OLED display illustrating the distance to the target surface, measured surface temperature, and the measurement status. Error bars represent the standard deviation from triplicate experiments. Recorded temperatures and the oral temperature for each volunteer. For each volunteer, the dots represent individual data points in the respective distance from the foreheads. Fever is a common symptom of many infections, e. 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. While screening for disease in the ongoing pandemic, rapid temperature measurements of many individuals quickly and safely without allowing the thermometer to be a vector of pathogen transfer are crucial, thus making contact infeasible, ruling out many of the above measurement sites. Yet, the onus is still on the user to operate them correctly for accurate measurements. To help alleviate the above problems, we describe the design and assembly of a low cost IR thermometer with distance and environmental temperature sensing capabilities to provide more accurate measurements. Experiments were conducted to validate compensation adjustments made in the algorithm, as well as the effects of measurements on different locations of the forehead. SR04 emits a 40 kHz ultrasound and computes the distance based on the time taken to detect the ultrasound wave reflected off an object. The electronic circuit, including the firmware. IR sensor, ultrasound sensor, Arduino Nano, LED bulbs, and OLED display. Five readings from the ambient and surface body temperature would be made and the average shown. Simultaneously, the ultrasonic sensor detects the distance from the target area and calculates the average of five readings. The compensation adjustment equation was derived from the regression analysis of the relationship between the oral temperature values and the measured values. Compensated values by the IR thermometer were used as the dependent value, while the measurement values by the IR thermometer and ambient temperature were each viewed as independent variables. Specifically, the area measured increases as the distance increases. The selected IR temperature sensor has a field of view of 80 degrees. Setting the average height of a human forehead of 58. IR temperature sensor can reliably measure the temperature of the target, is approximately 4 cm. Beyond this distance, flanking areas of the forehead would also be measured, affecting the accuracy. The ultrasound sensor consists of a transmitter sending an ultrasound wave and a receiver detecting the reflected wave by the targeted physical object. To ensure anonymity, a random volunteer ID between 1 to 1000 was generated for each volunteer entry. Three experiments were performed for this study. Volunteers were asked to avoid high intensity filexlib.
