Hi! Today we will discuss 2 different pulse sensor and their using shemas,codes.
Pulse sensors can be useful for your health projects. I will tell most easy way of using Pulse Sensor.
You can get libraries about pulse or a lot of useless codes.
You can get my other useful projects from >>> E.Levent <<< Please Follow me for new useful projects.
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.

Step 2: How Can We Use These?
Both of them have same features, and same pin.
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.
Step 3: Code;
