When we are talking about major vital signs of a human body, there are four major parameters that we need to be aware of, they are body temperature, heartrate, breathrate, bloodpressure, and due to COVID, oxygen saturation has become a major parameter that we need to be aware of. In this tutorial, we will be making a simple Arduino Nano 33 IoT-based device with multiple sensors. The device can measure some vital parameters of the human body. The device will be like a DIY multi-para monitor that you see in ICUs, a lot simpler and made of cheap sensors not meant for actual medical use. We will be using the new Arduino Nano 33 IOT for this purpose and we will try to make this device as simple as possible.In this article, we will build a complete IoT based health monitoring system that can measure and monitor all vital parameters of the human body. So, let's get started and for more Industrial IoT Solutions visit the website.
