About the Product

Heart Rate Sensor compatible with Arduino®

The DFRobot heart rate sensor is a thumb-sized heart rate monitor designed for Arduino microcontrollers. This sensor is developed based on PPG (PhotoPlethysmoGraphy) techniques. This simple and low-cost optical technique that can be used to detect blood volume changing in the micro-vascular bed of tissues. It is relatively easy to detect the pulsatile component of the cardiac cycle according to this theory.

The sensor has two holes that you can use to attach to your belt. You can wrap on your finger, wrist, earlobe or other areas where it has contact with skin.

This Product has another version, Arduino Heart Rate Sensor ECG, it has basically the same function but uses ECG electrodes instead.
