Joel Murphy and Yury Gitman, makers of the Pulse Sensor for Arduino, recently gave their product a complete overhaul. What emerged is the new Pulse Sensor Amped, and it’s now available in the Maker Shed. This version now contains built-in amplification and noise reduction circuitry allowing for faster, more reliable pulse readings. Not only that, it’s now 5V and 3.3v compatible so the same sensor that works with an Arduino Uno will work on a Lilypad Arduino. The Pulse Sensor is a great way to incorporate bio-feedback into your projects and give them that human element. To give you an example of what’s possible, here’s a project by Make alum Becky Stern that uses this sensor, a Mintduino, and an Open Heart kit to make a unique, flashing headband.
