Easy Pulse is a DIY pulse sensor that uses Photoplethysmography principle over a finger tip to detect the cardio-vascular wave or PPG signal. The sensor outputs a clean analog PPG signal as well as a digital pulse signal that is synchronous to the heart beat. The sensor can be interefaced to Arduino or any other microcontroller platform to make a DIY pulse meter or heart rate monitor. The sensor is designed by Embedded Lab and is now available from Elecrow for only $18.50.
