Low Cost Heart Rate Monitor Using Led-Led Sensor

Mostrar otras versiones (1)

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 light em...
