We've made some improvements and updates to our Pulse Sensor Arduino firmware and Processing software. Now, you can view the live Pulse Sensor data right in the Arduino Serial Potter! And our Processing Sketch has a much improved Serial Port selection process! Check it out!

The image below is from the Arduino Serial Plotter. The red trace is live heart beat data, the yellow trace is the time between each beat (IBI), and the blue trace is beats per minute (BPM).
The PulseSensor works with littleBits, via littleBits's "Proto Bit". Cool Stuff. You can now put your heartbeat into your littleBits projects !

Our Fall is starting out really great. We've got some new software examples that explore Heart Rate Variability (HRV) up on the Code and Guide page, and a few stories to tell.
First up: How To Do Open Source
We got a nice pingback from OHS Park and their Staff Pics this week. They picked Ladvien's great post on the trials and tribulations in the making of a Homemade Pulse Sensor. Two weeks ago, he was the Fail of the Week over at Hackaday. Glad to hear that he worked out the kinks in his process! Here at Pulse Sensor, we support open and honest copies and improvements. That's what Open Hardware is all about!
What Open Hardware is NOT about is disingenuous ripoffs and selling what amounts to a bill-of-goods (def. 2). That's what happened to an unwary shopper from Eastern Europe when he purchased what he thought was a legit Pulse Sensor, but then he received the hardware with an incomplete kit (no ear clip, velcro parts, vinyl stickers, or even a cable). We don't even know if the hardware they are selling works or not. Here's a link to the counterfeit Pulse Sensor from Good Luck Buy.
DO NOT BUY PULSE SENSOR FROM GOOD LUCK BUY the name says it all.
We love Open Hardware here at Pulse Sensor, and we understand the potential risks and rewards of releasing all of our design plans. And we also realize that getting cloned means that we must be doing something right... But that doesn't mean that we will put up with sub-standard ripoffs which sully the good name of our product!
If you don't buy the Pulse Sensor from us directly (which is fine! we also love our resellers!) make sure the company is reputable and trustworthy! The companies that we have re-seller agreements with are Adafruit, Sparkfun, and Maker Shed. If you are finding our Pulse Sensor at a different supplier, please be aware and double check the source!
We are releasing an informative new video today. It illustrates the best practices for setting up the Pulse Sensor as a Finger Strap or Ear Clip, and thus getting best readings from a user. For your viewing please, the video is narrated by the voice of Christopher Walken.
The new Arduino code contains an enhanced beat finding algorithm, and tidies up some inefficiencies since the last version.
We have also put together a detailed walk-through of the Arduino code for your edification.
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.
