Blood Pressure Measurement using in Wrist PPG and ECG

Continuous blood pressure monitoring with regular time intervals is used by auscultatory and oscillometric that conventional measurement techniques. The development of technology is increasingly sophisticated and makes it easier in various ways and of interest, especially in the research of measuring blood pressure and heart, various sensors used to help measure blood pressure, namely using the MXP5050DP sensor, Pulse Heart Rate Sensor as a Photoplethysmograph (PPG). AD8236 sensor from Sparkfun ECG. This study uses a sensor that is placed on the wrist. The beam of LED light detects the wrist area received by a series of receivers and then processed into digital data in the form of beats per minute (bpm) by the NodeMCU ESP8266 microcontroller. The data that is processed by NodeMCU ESP8266 will send data to the cloud server using the Ubidots IoT website to display the signal output. And the AD8232 sensor uses electrodes for a heart rate monitoring system using three-electrode sensors, also in this case it will research by applying the wrist electrode to analyze whether the output signal can be used for blood pressure.
