Measuring body temperature depends on the type of thermometer and measured body area. A thermometer placed on the tympanic membrane is considered ideal because the tympanic membrane and hypothalamus have arterial blood supply originating from the carotid artery (neck). Therefore, it is considered directly close to the core temperature. The Tympani Thermometer with external storage can facilitate the doctor's performance in diagnosing patients. This tool is designed using the MLX90614 sensor as a passive infrared sensor that can receive infrared energy from the tympanic membrane. The study aims to design a tympani thermometer. It compared the measurement results of the designed tool with ear thermometers that have been calibrated to get the error value. Based on the results, this prototype works well and has an error of 0.7°C in the left ear and an error of 0.24°C in the right ear.
The research discussed health services in the role of diagnostics and life support. The designed system was a system able to provide information on the user's health condition, in this case, a measure of heart rate and body temperature using a heart rate sensor (finger-tip sensor). It took the data from the blood flow on the index finger for 60 seconds, then displayed it on the LCD. The LM35 temperature sensor was used for body temperature data collection. Changes in the sensor heat would be converted into electricity, translated into digital form through a 10-bit ADC, processed by the ATMega 16 microcontroller, and displayed on the LCD. The results showed that the error of each parameter of heart rate and body temperature was <1.702% and <0.55%.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
