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

【MAX30102】The MAX30102 is a pulse oximeter biosensor module and built-in heart rate monitor. It integrates a red LED and an infrared LED, photodetector, optical device and low-noise electronic circuits with ambient light suppression. 【Compact Design】The MAX30102 uses a 18V power supply and a separate 50V power supply for internal LEDs. Use the device to measure heart rate and blood oxygen collection, and use it on fingers, earlobes, and wrists. 【Easy Operation】The standard communication interface supports I2C can transmit the collected values to the KL25Z and other microcontrollers to calculate heart rate and blood oxygen. 【Description】In addition, the chip can also turn off the module through the software, the standby current is close to zero, and the power supply is always maintained. The chip is widely used in Samsung Galaxy S series mobile phones. 【High Performance】Maximum LED 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).
