Hi guys

Let say I want to put together a circuit with a LED and Ambient Light Photo Sensor, and I want to detect the heart rate pulse through software (in a MCU). How do I do that?

Calculate a base line by window averaging then compare a reading to the base line to register a pulse??

Thanks guys!

Hi Dana

Thanks for the links, it looks like PSoC is a good fit for this kind of application. But for me, this is a learning exercise, so I am keen to find out how to calculate the baseline, and how to do a pulse detection in software.

Why not start by taking a whack at it by yourself?

Your first idea sounds reasonable, start coding!

I always do this as a mental exercise with any new problem, I ask myself "how could I accomplish this" - then go look at other people's solutions, after thinking it over.

Helps to understand and evaluate the solutions better.
