Heart rate is a very vital health parameter that is directly related to the soundness of the human cardiovascular system. This project describes a technique of measuring the heart rate through a fingertip using a PIC microcontroller. While the heart is beating, it is actually pumping blood throughout the body, and that makes the blood volume inside the finger artery to change too. This fluctuation of blood can be detected through an optical sensing mechanism placed around the fingertip. The signal can be amplified further for the microcontroller to count the rate of fluctuation, which is actually the heart rate.

Step 1: Sensor assembly

Picture of Sensor assembly
The sensor unit consists of an infrared light-emitting-diode (IR LED) and a photo diode, placed side by side, and the fingertip is placed over the sensor assembly, as shown below. The IR LED transmits an infrared light into the fingertip, a part of which is reflected back from the blood inside the finger arteries. The photo diode senses the portion of the light that is reflected back. The intensity of reflected light depends upon the blood volume inside the fingertip. So, every time the heart beats the amount of reflected infrared light changes, which can be detected by the photo diode. With a high gain amplifier, this little alteration in the amplitude of the reflected light can be converted into a pulse.

I'm supposed to do same project as a mini project for my college. BUT by using STM32f3 Discovery kit( ARM cortex m4).

Can i interface optocoupler pair with stm32f3 kit. if yes please tell me what all i require .

THANKS!!

PLEASE SEND THE INFO......

Done it, it was my first bigger project, and maybe too hard for beginner. But code is working only on PIC16F628A, but not on a PIC16F628

Hi

Could you please send me the source codes and a better detail about this project,I'll appreciate that...thanks (esmaeil.seraj09@gmail.com)

If we put pen or something instead of finger on the sensor then what will be your system response??

Does the sensor send other readings such as frequency?
