GY-MAX30102 pulse oximeter heart rate sensor module

MAX30102 Heartbeat Frequency Tester Heart Rate Sensor Module Puls Detection Blood Oxygen Concentration Test Geekcreit for Arduino – products that work with official Arduino boards.Light-dissolving method: measuring the pulse and blood oxygen saturation by using human tissue to cause different transmittance when the blood vessel beats; Light source: a specific wavelength of light-emitting diode selective for oxyhemoglobin (H bO 2 ) and hemoglobin ( Hb ) in arterial blood. The transmittance is converted into an electrical signal: the change in the volume of the arterial pulsation causes a change in the transmittance of the light. At this time, the photoelectric variator receives the reflected light from the human tissue, converts it into an electrical signal, and amplifies and outputs it.
