Other methods of calculating BPM #50

Closed NovaBringer closed 6 years ago

NovaBringer commented 6 years ago

Hey, I was wondering if there is another way of calculating a person's BPM without using the pulse sensor library. I know that you have to read the sensor, but I do not know how to continue after this.

The way to determine BPM is to first find the 'moment of heart beat'. Then, you need to measure time between that and the next 'moment of heart beat'. It is important to be as accurate as possible in the timing to get an accurate BPM. Please refer to this document for more information The code it discusses is superseded by the Pulse Sensor Library, but it has useful information. It has some links at the end for further reading.
