The MAX30102 is integrated pulse oximetry and heart-rate monitor biosensor module based on PPG ((PhotoPlethysmoGraphy). It is so small that you can just wear it on your finger or wrist for data collecting. Internally integrated 18bit ADC, the sensor supports I2C data output, which could be compatible with most controllers.
Features:
- For Heart-rate Measurement and SPO2 detection
- Working principle: Light-dissolving method - measuring the pulse and blood oxygen saturation by using human tissue to cause different light transmittance when the blood vessel beats;
Light source: a specific wavelength illuminating pole tube selective for oxyhemoglobin (HbO2) and hemoglobin (Hb) in arterial blood;
Transmittance is converted into electrical signal: the volume of the arterial pulsation is changed to the light transmittance of the light. At this time, the light is reflected by the human body tissue by photoelectric conversion, converted into an electrical signal and amplified and output.
- Extremely low standby current
- High sampling rate
- High SNR
