This heart beat sensor is designed to give digital output of heart beat when a finger is placed on it. When the heartbeat detector is working, the top-most LED flashes 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. Module dual output mode, digital output is simple, serial output with exact readings.

OVERVIEW
This heart beat sensor is designed to give digital output of heart beat when a finger is placed on it. When
the heartbeat detector is working, the top-most LED flashes 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. Module dual output mode,
digital output is simple, serial output with exact readings.
FEATURES
 Heart beat indication by LED
 Instant output digital signal for directly connecting
to microcontroller
 Total heart beat count can be obtained serially
(TTL) every minute
 Module dual output mode, digital output is simple,
serial output with exact reading
 Compact size
 Working voltage +5v DC
