Gravity: PPG Heart Rate Monitor Sensor for Arduino (Analog/Digital) Rain Sensor Operating humidity range: 0 ~The DFRobot heart rate sensor is a thumb sized heart rate monitor designed for Arduino microcontrollers. This heart rate monitor sensor is a pulse sensor which is developed based on PPG techniques. This is a simple and low cost optical technique that can be used to detect blood volume changing in the microvascular bed of tissues. It is relatively easy to detect the pulsatile component of the cardiac cycle according to this theory. The sensor has two
