Pulse sensor kit

The Pulse Sensor Kit is a kit.  It does contain an assembled PCB Pulse Sensor, but it also has a collection of other supplies that you need to get the most out of the Pulse Sensor: a Velcro strap (to wrap the sensor around your finger), an ear clip, and vinyl dots (to make the sensor more comfortable and reliable when contacting direct skin).

Heart Rate data can be used in many Electronic design and microcontroller projects. But the heart rate data is difficult to read, however the Pulse Sensor help us to read heart rate. The Pulse Sensor is more of a 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.

It essentially combines a simple optical heart rate sensor with amplification and noise cancellation circuitry making it fast and easy to get reliable pulse readings.
