IOT platform for vital signs detection using node microcontroller

Abstract

Using IoT technology to monitor patients' vital signs can help limit the spread of the coronavirus. Therefore, a cost-effective remote monitoring system measuring vital signs is proposed. Dual heart rate and oxygen level sensor, a temperature sensor, two microcontrollers, UNO as a power supply, and Node as the main controller are used in this system. The vital signs are monitored non invasively utilising Photoplethysmography equipment and wirelessly relayed to the person involved via the Blynk platform utilising a Wi-Fi device. Photoplethysmography is the core technology for the entire system. It also shows how the system can connect to the internet worldwide, which lets it be used in different clinical tests.
