Description
Description
This heart rate monitor circuit functions on the principal of photographically: The change in the volume of blood in any organ causing a change in the light intensity through that organ. Here, A Light from an LED will be transmitted through any region of the body such as a finger and will then be received by an IR receiver.This heart rate monitor circuit functions on the principal of photographically: The change in the volume of blood in any organ causing a change in the light intensity through that organ.
