Introduction: MAX30102 is a module of a integrated pulse blood oxygen instrument and a heart rate monitor biosensor.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 Arduino 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 Samsung Galaxy 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.
