TECNOIOT 5pcs MAX30102 Heart Rate Sensor Pulse Detection Blood Oxygen Concentration Test

【MAX30102】The MAX30102 is an integrated pulse oximeter and heart rate monitor biosensor module. It integrates a red LED and an infrared LED, photodetector, optical device, and low-noise electronic circuitry with ambient light suppression. 【Design compact】The MAX30102 uses an 18V power supply and a separate 50V power supply for internal LEDs. Wear the device for heart rate and blood oxygen collection, and wear it on your fingers, earlobes and wrists. 【Easy operation】The standard I2C-compatible communication interface can transmit the collected values to the KL25Z and other microcontrollers for heart rate and blood oxygen calculation. 【Descripcion】In addition, the chip can also shut down the module through software, the standby current is close to zero, and the power supply is always maintained. The chip is widely used in the Samsung Galaxy S series mobile phones. 【High Performance】LED peak wavelength: 660nm/880nm; LED supply voltage: 3.3~5V; Detection signal type: Light reflection signal (PPG); Output signal interface: I2C interface; Communication interface voltage: 18~3.3V~5V (optional).
