MAX30102 Blood Oxygen Concentration Wrist Heart Rate Pulse Detection Heartbeat Sensor Module STM32 Sensor

Introduction:
MAX30102 is a module of a integrated pulse blood oxygen and heart rate monitor. It integrates a red light LED and an infrared LED, photoelectric detector, optoelectronic device, and low -noise electronic circuits with ambient light.
MAX30102 uses a 1.8V power supply and an independent 5.0V for internal LED power supply. It is applied to wearable devices for heart rate and blood oxygen collection detection, wearing fingers, earlobe and wrist. Standard I2C compatible communication interfaces can transmit the collected values to single -chip microcomputers such as Ard*uino and KL25Z for heart rate and blood oxygen calculation. In addition, the chip can also cut the module through the software, and the current is close to zero, and the power supply always maintains the power supply state. Because of its excellent performance, the chip has been applied to the Sam*sung Ga*laxy S series mobile phone. Compared with the previous generation MAX30100, the chip integrates glass lids to effectively eliminate external and internal light interference, and has the optimal and reliable performance.

Description
Main parameters:
LED peak wavelength: 660nm/880nm
LED power supply voltage: 3.3 ~ 5V
Detection signal type: Light reflection signal (PPG)
Output signal interface: I2C interface
Communication interface voltage: 1.8 ~ 3.3V ~ 5V (optional)
Panel reserved assembly hole size: 0.5x8.5mm

Principle description:
· Optical solution accumulation method: The use of human tissue during blood vessels causes different light transmission rates to enter
Ring pulse and blood oxygen saturation measurement;
· Light source: Using oxygenocyte (HBO2) and hemoglobin in the arterial blood
(HB) Selective light -emitting diode;
· The transformation of light transmission is transformed into a telecommunications signal: arterial pulsation and congestion volume causes the light transmission rate of this beam of light. At this time, the photoelectric converter receives the anti -body light via the human tissue, transforms into a electrical signal and amplifies and output.
