Problems solved by technology

[0003] The pulse rate detection device is an electronic instrument used to measure the beating times of a person's pulse and heart rate. It is also the main component of the electrocardiogram. Therefore, it plays an important role in modern medicine and can reflect many physiological and pathological conditions in the human cardiovascular system to a large extent. Therefore, it has high medical value and application prospects for pulse wave acquisition and processing. Currently, there are many types of pulse rate detection instruments on the market, but there are not many pulse measurement devices that can achieve accurate measurement, and the biological signal of the human body Most of them are low-frequency weak signals in the background of strong noise, and the pulse wave signal is a low-frequency weak non-electrophysiological signal. Pulse rate signal with higher signal-to-noise ratio, weak anti-motion interference ability and anti-saturation ability
