Finger Clip Heart Rate Pulse Sensor that is designed for hobbyists and educational applications, It is used to illustrate the principle of phot plethysmography (PPG), PPG is a non-invasive technique for detecting the cardio-vascular pulse wave from a fingertip. The Easy Pulse Sensor uses a transmission mode PPG probe (HRM-2511E) sensor. This Sensor uses an infrared light source to illuminate the finger on one side, and On the other side of the sensor there is a photodetector that measures small variations in the transmitted light intensity due to changes in blood volume inside the tissue. The onboard components & instrumentation provide a clean and filtered analog PPG waveform. The on-board LED also indicates the digital pulse output. The analog and digital signals are both synchronous with the heartbeat. Package Includes : 1 x Finger Clip Heart Rate Pulse Sensor
