We are announcing a big big upgrade to the Pulse Sensor today, with the release of Pulse Sensor Amped!
Pulse Sensor Amped adds
amplification and noise cancellation circuitry to our original Pulse Sensor hardware. It's
noticeably faster and easier to get reliable pulse readings. Also, Pulse
Sensor Amped works with either a 3Volt and 5Volt Arduino. We've
discontinued our previous Pulse Sensor models because this one is so darn good.
Lastly, we've also streamlined and improved the included Processing visualization software and Arduino code. This is our 3rd generation Pulse Sensor, and definitely our sweetest hardware and software creation to date.
