Heart rate sensor

Description

Use: This probe lets you measure and visualize the heart rate of a subject. Unlike an electrocardiograph which reads the electric signals of the heart, the heart rate sensor measures the subject’s blood flow. The probe’s clip is fixed to the ear lobe or at the tip of a finger. On one end of the clip an electroluminescent diode emits infrared radiation’s, while a phototransistor receives them at the other end. As the heart beats, it pumps more blood in the vessels. This creates a variation in the intensity of the infrared rays which travel through the ear lobe or fingertip. With the use of the GALILEO interface, you can easily interpret this voltage variation to visualize the heart rate of the subject.
