  • method:
  • measuring

  • and

  • by
  • using

  • to
  • cause

  • transmittance
  • when

  • source:
  • a

  • wavelength
  • of
  • light-emitting
  • diode
  • selective
  • for
  • oxyhemoglobin
  • (H
  • bO
  • 2
  • )
  • and
  • hemoglobin
  • (
  • Hb
  • )
  • in
  • arterial
  • blood; The
  • transmittance
  • is
  • converted
  • into
  • an
  • electrical
  • signal:
  • the
  • change
  • in
  • the
  • volume
  • of
  • the
  • arterial
  • pulsation
  • causes
  • a
  • change
  • in
  • the
  • transmittance
  • of
  • the
  • light.
  • At
  • this
  • time,
  • the
  • photoelectric
  • variator
  • receives
  • the
  • reflected
  • light
  • from
  • the
  • human

  • This
  • is
  • a
  • demo
  • to
  • show
  • the
  • reading
  • of
  • heart
  • rate
  • or
  • beats
  • per
  • minute
  • (BPM)
  • using
  • a
  • Penpheral
  • Beat
  • Amplitude
  • (PBA)
  • algorithm.

  • It
  • is
  • best
  • to
  • attach
  • the
  • sensor
  • to
  • your
  • finger
  • using
  • a
  • rubber
  • band
  • or
  • other
  • tightening
  • device.
  • Humans
  • are
  • generally
  • bad
  • at
  • applying
  • constant
  • pressure
  • to
  • a
  • thing.
  • When
  • you
  • press
  • your
  • finger
  • against
  • the
  • sensor
  • it
  • varies
  • enough
  • to
  • cause
  • the
  • blood
  • in
  • your
  • finger
  • to
  • flow
  • differently
  • which
  • causes
  • the
  • sensor
  • readings
  • to
  • go
  • wonky.

  • Hardware
  • Connections
  • (Breakoutboard
  • to
  • Arduino):
  • -5V

  • The

  • can
  • handle
  • 5V

  • 3.3V
  • I2C
  • logic.
  • We
  • recommend
  • powering

  • board
  • with
  • 5V
  • but
  • it
  • will
  • also
  • run
  • at
  • 3.3V. */
