An easy way to send your heartbeat to the Cloud using arduino

This cool (and very low price) sensor is attached on your ear and can detect your heart’s pulse through transmitting infrared light and checking the absorption variation caused by the blood flow on your ear lobe. The site of the products provides also the Arduino code for detecting the beats and calculating an average heart rate (in bpm  - beats per minute). The sensor comes with a grove connector, so setti ...
