A high sensitivity, low power and low cost sensor has been developed for photoplethysmography (PPG) measurement. The PPG principle was applied to follow the dilatation and contraction of skin blood vessels during the cardiac cycle. A standard light emitting diodes (LEDs) has been used as a ...
This is the most tricky part of the project. You will have to map down when your heart beats on the sensor. The basic idea is that when the led is on and shines to the LDR the reading is about 1020. When finger is inserted on the LDR the value changes between 980-995. This is ...
How does the heart rate monitor work? The app is based on contact photoplethysmography (finger is in contact with the built-in camera) which can basically detect changes of the light absorption caused by the pulsation of arterial blood volume. ...
