Heart rate and body temp are very important, we made this project for health care in the school, you can ask me anything about the project.
Both of heart rate and body tempare directly related to the soundness of the human cardiovascular system, this was my general idea of creating such project.
This project describes a technique of measuring the heart rate through a fingertip using an arduino nano.
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.
heart rate sensor function
Heart rate is the number of heartbeats per unit of time and is usually expressed in beats per minute (bpm). In adults, a normal heart beats about 60 to 100 times a minute during resting condition. The resting heart rate is directly related to the health and fitness of a person, and hence is important to know. You can measure heart rate at any spot on the body where you can feel a pulse with your fingers. The most common places are wrist and neck. You can count the number of pulses within a certain interval (say 15 sec), and easily determine the heart rate in bpm.
Body temp sensor function
as i'm just trying to make it a short descreption, i will give more details about this sensor to whoever intersted.
Photos of my project
if you are intersted in repeating this project please send me private message with your email and i will contact with you as soon as possible.
