说明
- MAXREFDES1043, Reference Design for the MAXREFDES1043 is designed for SpO2 measurements based on new-generation biosensor MAX30102. The MAXREFDES1043 is a high-accuracy, low-power, small-size and easily implemented design that can monitor SpO2 levels using red and IR LEDs. The MAX30102 is an integrated pulse oximetry and heart-rate monitor module. It includes internal LEDs, photodetectors, optical elements and low-noise electronics with ambient light rejection. The MAX30102 provides a complete system solution to ease the design-in process for mobile and wearable devices. It operates on a single 1.8V power supply and a separate 3.3V power supply for the internal LEDs. Communication is through a standard I2C-compatible interface. The module can be shut down through software with zero standby current, allowing the power rails to remain powered at all time
