Heart Beat Sensor
[attachment=22107]
Heart Beat Sensor
Heart beat sensor is designed to give
digital output of heat beat when a finger is
placed on it. When the heart beat detector
is working, the beat LED flashes in unison
with each heart beat. This digital output
can be connected to microcontroller
directly to measure the Beats Per Minute
(BPM) rate. It works on the principle of
light modulation by blood flow through
finger at each pulse.
Features
· Heat beat indication by LED
· Instant output digital signal for directly connecting to microcontroller
· Compact Size
· Working Voltage +5V DC
Applications
· Digital Heart Rate monitor
· Patient Monitoring System
· Bio-Feedback control of robotics and applications
Using the Sensor
· Connect regulated DC power supply of 5 Volts. Black wire is Ground, Next middle wire is
Brown which is output and Red wire is positive supply. These wires are also marked on PCB.
· To test sensor you only need power the sensor by connect two wires +5V and GND. You can
leave the output wire as it is. When Beat LED is off the output is at 0V.
· Put finger on the marked position, and you can view the beat LED blinking on each heart
beat.
· The output is active high for each beat and can be given directly to microcontroller for
interfacing applications.
