1. Max31002 is a module of integrated biological sensor of pulse oximeter and heart rate monitor. It integrates a red LED, an infrared LED, a photoelectric detector, an optical device, and a low noise electronic circuit with ambient light suppression.
2. Max31002 uses a 1.8V power supply and an independent 5.0V power supply for internal led, which is used for heart rate and blood oxygen collection and detection on wearable devices, and is worn on fingers, earlobes, wrists, etc.
3. The standard I2C compatible communication interface can transmit the collected data to kl25z and other single-chip computers for heart rate and blood oxygen calculation.
4. In addition, the chip can turn off the module by software, and the standby current is close to zero, so that the power supply can always maintain the power supply state.
5. Because of its excellent performance, the chip is widely used in mobile phones for Samsung Galaxy S7. Compared with the previous product MAX3100 (MAX3100 is out of production at present), max3102 integrated with glass cover can effectively eliminate external and internal light interference, and has the best and reliable performance.
6. The heart rate and blood oxygen sensor module is a biosensor module made according to the power requirements of max31002.
7. Its I2C communication interface voltage is compatible with 1.8v/5v, and it can communicate with conventional MCU development boards such as kl25z, STM32, etc.
8. In addition, it also provides the corresponding heart rate and blood oxygen program, which can be easily used with a variety of development boards to complete the monitoring of heart rate and blood oxygen concentration.
9. It is suitable for scientific research and teaching demonstration of heart rate and blood oxygen, and also suitable for secondary development.
