Design and Development of an Arduino Mega-Based Sphygmomanometer Calibrator for Simultaneous Pressure and Time Measurement

Abstract

A sphygmomanometer is used to measure a person's blood pressure. The accuracy of the sphygmomanometer is very important in the world of health because it affects the diagnosis and treatment of patients. To find out the accuracy level of the sphygmomanometer, calibration can be carried out which is currently still being carried out using several calibrators such as digital pressure meters and digital stopwatches. Objective: to design an Arduino Mega-based sphygmomanometer calibrator that can measure pressure and time parameters simultaneously with a single calibrator. Research Method: designed a sphygmomanometer calibrator using the MPX -5050GP Pressure Sensor as a pressure measurement reader and Arduino Mega 2560 as a microcontroller. Results: the time accuracy value had an error percentage of 0.10% with a maximum accuracy of 99.92%. Meanwhile, the pressure accuracy value was obtained with an error percentage of 0.0284% with a maximum accuracy of 100%. Conclusion: the measurement results obtained have high accuracy and a low error percentage so that Arduino Mega-based sphygmomanometer calibrator can be used effectively and accurately
