Arduino Based Pulse Oximeter
The objective of a pulse oximeter in IoT (internet of things) is to monitor and measure the oxygen saturation (spo2) and heart rate of an individual remotely and in real time using a connecting device. pulse oximeters are small, non -invasive medical devices that are typically attached to a fingertip or other part of the body, and they use infrared light to measure the amount of oxygen carried by haemoglobin in the blood.
