The Geek Pub guide will help get you started with an Arduino pulse sensor. While sensors like this are reliable, it's worth keeping in mind that your heart rate can tell you a lot of different things.

This is an Arduino-based Proximity Sensor circuit wired using the popular HC-SR04 Ultrasonic ranging module,used here for non-contact object detection purpose. The HC-SR04 module includes ultrasonic ...

The Withings Pulse is the latest device in the personal activity tracker category, and it isn't a wristband, which runs counter to the latest fad. Instead, it's a portable rectangle not unlike the ...

The organic optoelectronic pulse oximetry sensor described here demonstrates the potential for the application of organic electronics to thrive in the medical device field.

A basic microcontroller can be used to convert a sensor's analog output into a pulse train, thereby making the output compatible with standard digital I/O ports.

Pulse Oximeters are an essential hospital tool and serious athletes rely on them to track the efficiency with which they pump oxygen into their blood stream. Masimo's new iSpO2 puts these rather ...

I recently had to build an infrared close proximity sensor that could tell if something was dropped in a parcel delivery drop box. After some searching, I ended up using a microcontroller and a piece ...
