Heart rate data can be really useful whether you’re designing an exercise routine, studying your activity or anxiety levels, or just want your shirt to blink with your heartbeat. The problem is that the heart rate can be difficult to measure. Luckily, the Pulse Sensor can solve that problem!

The Pulse Sensor is a plug-and-play heart-rate sensor for Arduino. It can be used by students, artists, athletes, makers, and game & mobile developers who want to easily incorporate live heart-rate data into their projects. It essentially combines a simple optical heart rate sensor with amplification and noise cancellation circuitry making it fast and easy to get reliable pulse readings. Also, it sips power with just 4mA current draw at 5V so it’s great for mobile applications.

Simply clip the Pulse Sensor to your earlobe or fingertip and plug it into your 3 *or *5 Volt Arduino and you’re ready to read heart rate! Of course, the Arduino example code is available as well as a Processing sketch for visualizing heart rate data.
