Pulse Sensor Amped works with either a 3Volt and 5Volt Arduino.\u003c\/p\u003e\n\u003cp\u003eThe kit includes:\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eA 24-inch Color-Coded Cable, with a standard male header connectors. Plug it straight into an Arduino or a Breadboard. No soldering is required.\u003c\/li\u003e\n\u003cli\u003eAn Ear Clip, perfectly sized to the sensor.  We searched many many places to find just the right clip.  It can be hot-glued or epoxied to the back of the sensor to get reading from an ear lobe.\u003c\/li\u003e\n\u003cli\u003eParts to make a handy Velcro Finger Strap. This is another great way to get heart-rate data.\u003c\/li\u003e\n\u003cli\u003e4 Transparent Stickers, to insulate the front of the Pulse Sensor from oily fingers and sweaty earlobes.\u003c\/li\u003e\n\u003cli\u003eThe Pulse Sensor has 3 holes around the outside edge which make it easy to sew it into almost anything.\u003c\/li\u003e\n\u003cli\u003eVisualization software (made in Processing) to instantly see output of the sensor and for troubleshooting.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eWhen the Pulse Sensor Amped is just sitting there, not in contact with any fingers or earlobes or other parts, the analog signal hovers around the mid-point of the voltage, or V\/2. When Pulse Sensor Amped is in close contact with your fingertip or earlobe (or other part) the change in reflected light when blood pumps through your tissues makes the signal fluctuate around that reference point. In the image below the horizontal line is at V\/2.\u003c\/p\u003e\n\u003cp\u003eArduino watches the analog signal from Pulse Sensor, and decides a pulse is found when the signal rises above the mid-point. That's the moment when your capillary tissues gets slammed with a surge of fresh blood. Then, when the signal drops below the mid-point, Arduino sees this and gets ready to find the next pulse. There's also built in hysteresis to the rising and falling thresholds which you can adjust if necessary.\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e","brand":"PulseSensor","offers":[{"title":"Default Title","offer_id":707189945,"sku":"PSA001","price":20.95,"currency_code":"EUR","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0174\/1800\/products\/PSA_001.jpg?v=1398345632","url":"https:\/\/shop.pimoroni.com\/en-eu\/products\/pulse-sensor-amped","provider":"Pimoroni Ltd","version":"1.0","type":"link"}
