Design and Implementation of IoT Based Blood Pressure Monitoring Tools

Abstract

Blood pressure is an indicator of various diseases in the body such as high blood pressure, coronary heart disease, kidney disease and others, while currently the public needs help from agencies that have knowledge related to measure blood pressure. So that people can know and measure blood pressure independently without having to go to agencies that can take measurements, we need a tool that can measure blood pressure automatically and provide measurement statistics so that the public or patient can monitor the state of their blood pressure. In this paper, we will try to integrate digital blood pressure measuring devices with IoT (internet of things) using Arduino to process sensor values from MPX5050DP and NodeMCU to connect to the internet so that they can connect to firebase which acts as a database. The results of measurements using a blood pressure monitoring tool that we made using the MPX5050DP are not much different from those produced by a digital blood pressure measurement device from Omron. After the results are compared and processed with the relative error equation it produces 3.83% for systole and 2% for diastole and obtained an average of 13.94 s for the delay of each data transmission.
