With this heart rate sensor and pulse oximeter you can easily read information from a person such as heart rate (in graph), heart rate (in BPM), SPO2 and body temperature via a finger. A library of this module can be downloaded via the library manager in the Arduino IDE.
For reliable measurements, keep the finger on the sensor with constant pressure (ideally an elastic band is used).
