Arduino measures heart beat rate from fingertip

Raj of Embedded Lab writes: The PIC16F628A based heart rate meter is one of the most popular projects published on Embedded Lab. In this article, I am going to show how to replicate the same project using a simpler platform like Arduino. The Arduino heart rate meter will use Arduino Uno, Easy Pulse Plugin, and 4-digit […]

Easy Pulse Plugin, an Arduino pulse sensor

Raj over at Embedded Lab has written an article detailing the new version of their Easy Pulse Sensor: the Easy Pulse Plugin, an Arduino and chipKIT compatible pulse sensor based on Photoplethysmography Today we are happy to announce the release of a new addition to our Easy Pulse Sensor series named Easy Pulse Plugin. Like its predecessors, the original Easy […]

Easy Pulse V 1.1 project update

Raj previously designed the Easy Pulse heart rate sensor. Now he informs us of an update: “I would like to inform you about the release of a new version of Easy Pulse sensor. The Easy Pulse sensor is designed for hobby and educational applications to illustrate the principle of photoplethysmography (PPG) as a non-invasive optical […]

DIY photoplethysmographic pulse sensor

Raj has posted a tutorial about a DIY photoplethysmographic sensor for measuring heart rate from fingertip. “The sensor measures the little variations in the blood volume inside finger tissue and outputs a digital pulse which is synchronous with the heart beat.” The sensor used in this project is TCRT1000, which is a reflective optical sensor […]

Maker Shed pulse sensor

The folks over at MAKE have a pulse sensor which attaches to your fingertip or earlobe and measures minute changes in light from expansion of the capillary blood vessels to sense your heartbeat. Technical information is available here, including design files, sample code and schmetic. The device is licensed under the TAPR Open Hardware License. […]

Pulse sensors for Arduino

Joel Murphy and Yury Gitman of are developing an Arduino compatible pulse sensor. “Pulse Sensor” is a well-designed 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. After a few months of testing […]
