Finger heartbeat measuring sensor module for Arduino and other microcontroller projects

 
This module uses abright IR LED and a phototransistor. When a finger is placed between the LED and transistor you will get an analogue output of light intensity that passes through the finger, this will vary every time the heart beats and indicate heart rate.
 
Voltage : 5VDC
Size 19x15mm
