PC-based heart rate monitor using Arduino and Easy Pulse sensor

Raj writes that he’s just finished a new PC-based heart rate monitor using Arduino and Easy Pulse sensor (see previous Easy Pulse post). This project takes the sensor’s analog photo-plethysmography (PPG) output and feeds it into an Arduino ADC channel which converts it into digital counts which are then transferred to the PC through a […]

Easy Pulse heart rate sensor

Easy Pulse is a heart rate monitor using an IR LED and a light detector: Easy Pulse provides a reflective IR sensor with necessary instrumentation circuit to illustrate the principle of photoplethysmography as a noninvasive technique for measuring heart rate. In order for this sensor to work, the fingertip should be placed gently over the […]
