DFRobot Expansion Board Ppg (Photoplethysmography) Development Kit for SEN020 Arduino

The DFRobot heart rate sensor is a thumb-sized heart rate monitor designed for arduino microcontroller. It include a gravity interface for easy plug-and-play connectivity. This sensor is a pulse sensor which is developed based on PPG techniques.

• It is simple and low-cost optical technique
• It is relatively easy to detect the pulsatile component of the cardiac cycle
