Body temperature is a sensitive and reliable indicator of physiological integrity to determine the patient's physical status and disease progression. In finding signs of clinical disease, medical professionals must measure body temperature using a thermometer. Getting a core temperature measurement that accurately reflects actual body temperature is very important. The ideal method for measuring a person's temperature should be accurate, fast, and reflect core temperature. Meanwhile, the temperature reading method is non-invasive, non-traumatic, easy to use, and hygienic for everyone. A thermometer that reflects this utilizes the infrared energy released by the patient's tympanic membrane temperature to read. To solve this problem, this study makes an ear thermometer module using the MLX90614 sensor as a passive infrared sensor that can receive infrared energy from the tympanic membrane. In the research and manufacture of the module using a pre-experimental method, the measurement results are compared with a forehead thermometer calibrated to get a high level of accuracy on the tool making. Based on body temperature data compared to "IR Thermometer Model IT-122,"the % error value on the forehead temperature reading shows a high % error value caused by the inability of the sensor to read the temperature on the forehead accurately. This study found that the infrared diagnostic accuracy of tympanic temperature measurement was not inferior to forehead temperature measurement. After testing the system, the tool can be used according to its function and purpose.
