Implementation of Non-Invasive Measurement of Blood Pressure, Heart Rate and Oxygen Saturation Monitoring System based on Internet of Things

Abstract

Regular health checks have become very popular to prevent health disorders in particular to maintain the health condition of the body. Body condition very big influence on human health, the human daily activity as well as in blood pressure in humans are very big influence for kesehatan.pembacaan continuous blood pressure cuff sphygmomanometer konvensional.teknik system microcontroller-based measurement of non-invasive continuous done for blood pressure measurement in which no cuff is used and the signal is taken only from the finger. It does not give pain to humans because there is no pressure on arms needed to measure blood pressure. A sensor network consisting of a light emitting diode and light dependent resistor is used to get the value of heart rate and oxygen saturation in the blood and processed by using algroritma resulting in a value of blood pressure. Variations in blood volume in the finger is measured with an optical sensor. automatic detection algorithm based on the peak that is used to detect heart rate continuously in accordance with the systolic and diastolic pressures with some simplifications. The proposed system is controlled by the microcontroller NodeMCU who have esp8266 WiFi module that can be connected to smartphones to Internet-based periodic monitoring of things. Researchers measured blood pressure continuously with a 20 second delay between adjacent readings during the measurement of the heart rate
