Description:
l The electrocardiogram signal on the palm of the human body is obtained through the metal electrode on the handle, and after signal conditioning such as amplification and filtering, the R wave is extracted and shaped and output, and finally the heart rate signal is converted into a square wave signal that can be directly measured by the microcontroller. When the human heart rate beats, a high level of a certain width is generated
