Heart Rate Sensor on Oled Display Using Arduino

Heart Beat Sensor is used blood pressure and body temperature are very important parameters to known for human body. We go to doctors that use different kinds of apparatuses to know the heart beat of a human. In this tutorial, we are going to make our own heart beat sensor that will tell us the heart rate. We will make an Arduino based heart beat sensor that will tell us the number of pulses in a minute when we will place a finger on it.

Working of Heart beat sensor
The module uses an infrared led (IR) and a photo transistor to detect the pulse of the finger and whenever a pulse is detected, red led flashes. There will be led on the light side of the finger and a photo transistor on the other side of the finger. Photo transistor is used to obtain the flux emitted. The resistance of the photo resistor will change when the pulses will change.
The output graph will display on Oled display .
