Step 1: How Many Sensors Are There About Pulse?

There are 2 different popular pulse sensor.

  • What is the diversity?
  • First sensor is cheaper than other. Because it is dud! If you want to work stabile.

I am regret because I bought first one.:(

Don't Buy first one because its' logic is; a led bright to an ldr, and save the bright changes. When you couldn't turn led to true position, values will be wrong!

But if you use second one; You don't have to deal with values. Because it is an intigret system. Just hold your hands and get the values.

They have 3 pins; one of them signal, second +5v and third one Gnd.

You don't have to use a library for this sensor.

Connect the signal pin to an analog pin.
