Project on Simple Digital Heart Rate Monitor

The aim of this project is to implement an ECG and Digital Heart Rate counter. The main challenges include amplifying the desired weak signal in the presence of noise from other muscles and electrical sources. A display of the heart rate will be obtained by measuring the time between signal peaks and then calculating the frequency of the peaks in units of beats per minute.
The device is most useful if it is portable. This requires a battery to be able to power all of the necessary components as well as the power output of the battery to be regulated.Our implementation of the heart monitor involves low cost amplifier and filter components coupled with a sophisticated microcontroller and LCD screen.
Results were successful for the amplifier filter stage of the implementation with an ECG successfully detected and recorded but variability of the voltage points complicated the calculation and display of the actual rate.

  3. Hello fantastic website! Does running a blog similar to this require a massive amount work?
    I have absolutely no understanding of programming however I had been hoping to start my own blog in the near future.
    Anyway, if you have any recommendations or techniques for new
    blog owners please share. I know this is off
    topic nevertheless I simply needed to ask. Thanks!

  5. I was wondering if you ever thought of changing the page layout of your blog?
    Its very well written; I love what youve got to say. But maybe you could a little more in the way of content
    so people could connect with it better. Youve got an awful lot of text for only having one or 2 images.
    Maybe you could space it out better?

  6. Hmm it seems like your blog ate my first comment (it was extremely long) so I guess I'll just sum it up what I submitted and say, I'm thoroughly enjoying your blog.
    I as well am an aspiring blog writer but I'm still new to everything. Do you have any points for rookie blog writers? I'd certainly
    appreciate it.
