Heart Rate Pulse Sensor Module

Heart Rate Pulse Sensor Module [3V, 5V]  is a small plug-and-play heart-rate sensor for Arduino projects. It is easy to install and use, so most of the user such as student, sport-mans, artists, and developers, can easily apply live heart-rate data into their projects. The heart rate data is important to diagnosis and study human health, anxiety levels, activity or body health factors. This sensor is based on two essential parts of a simple optical heart rate sensor with amplification and noise cancellation. It is a fast response, reliable, and also a low power consumption with 4mA current, which is idealized for portable and battery supplied applications.
While using, simply clip the sensor to your fingertip or earlobe and through the three pine terminals plug it into the 3V or 5V DC Arduino boards.
