Project Background

• Currently there are many heart rate monitors in
  use that enable a user to check up on his or her
  own heart health, but there are not many
  applications using heart rate monitors that allow
  users to save their heart rate data to view later
  for medical purposes. Many existing monitors are
  also bulky and hard to use, and also sometimes
  unreliable.
• The purpose of the Optical Heart Monitor project
  is to develop a cheap, reliable, easy to use
  heart monitor that not only gives real time data,
  but is able to store the data to see changes over
  time.

Statement of Work

• Project Features
• Signal Collection
• Improve upon previously designed optical heart
  rate collection circuitry.
• Use designed circuitry to obtain analog signal of
  the users heart rate.
• Analog to Digital Signal Conversion / Signal
  Processing and Filtering
• Take analog signal of users heart rate and
  manipulate using digital filters to obtain time
  differences between heart beats from the optical
  sensor.
• Interface to Existing Code
• Implement code that calculates the heart rate
  from the time differences between heart beats.
• Enable heart rate data to be saved onto external
  flash memory.
• Integrate code that allows the heart rate data to
  be read from device just like a USB jump drive on
  a computer.
• Integrate Components / Construct PCB
