One of the health conditions to note is to keep blood pressure. many people sick one cause is high blood pressure. there are two methods of measuring blood pressure ie invasive and non-invasive. using the oscillometric method the measurement can be performed automatically, with the help of a piezoresistive pressure sensor connected to arduino mega 2560. so that the measurement data in the form of name, age, and blood pressure can be stored on the SD card that can be read again if needed. In this research the difference between the systolic or diastolic values of blood pressure reading with analog devices compared with automatic blood pressure reading tool and obtained that the average difference of 3,265 mmHg for systolic value and 6,165 mmHg for diastolic. Then this difference is used in the calibration process so that the result of automatic blood pressure reading tool is better. The result of calibration reading tool has 99.47% - 99.82% accuracy Keywords: Arduino, Blood pressure, Oscillometric, Pressure Sensor.. 1. Introduction High blood pressure is one cause of death or severe illness[1]. Hypertension is a silent killer disease or so-called "the silent kill- er" because the original cause is unknown or without symptoms at all. Hypertension can cause various complications that can lead to several other diseases, such as heart disease, blindness, kidney and stroke until death. According to RISKESDAS (Basic Health Re- search) in 2010 hypertension can attack anyone, various age groups also socioeconomic status. Hypertension disease in Indo- nesian population aged 18 years and over is 31.7% of the total population in Indonesia. People suffering from hypertension should take regular blood pressure measurements, because blood pressure is a vital sign of humans that can change over time. Measuring blood pressure can be used as a benchmark for patients in seeking medical help to assist their condition. There are some microcontroller can be used in system that is [2]ATMega, [3]Arduino, ARM, etc. In this research we are used Arduino. Measuring blood pressure can be done anywhere. By having a blood pressure meter itself, hypertension patients can measure their blood pressure and know when to meet health workers. In this Research the author tries to design and make digital blood pressure monitoring system that can be used easily and efficiently. [4]The automatic blood pressure monitor system equipped using ARM and DSP have been promoted. [5] This paper is used GSM to transfer data from Automatic blood pressure to SD card to save the data measurement. In this paper the automatic blood pressure monitor system equipped with data storage using arduino mega 2560. 2. Method The block diagram automatic blood pressure monitor system equipped with data storage using arduino mega 2560 can be de- scribed in Fig. 1. Fig. 1: The System Block Diagram
