Heart Rate Monitor Sensor For Arduino Gravity
The DFRobot Heart Rate Sensor is a compact, thumb-sized pulse sensor based on PPG (PhotoPlethysmoGraphy) technology. This optical method detects changes in blood volume within the microvascular bed of tissues, making it simple and cost-effective for measuring the pulsatile component of the cardiac cycle.
You can attach the sensor to your finger, wrist, earlobe, or other skin-contact areas using the included wrist belt or mounting holes. With its Gravity interface, setup is plug-and-play, making it easy to connect to Arduino, Raspberry Pi, Intel Edison, Joule, or Curie boards. Operating at 3.3V–6V, it’s both versatile and beginner-friendly.
