The MAXREFDES1043 design is based on Maxim's new generation biosensor MAX30102, which enables SpO ₂ measurement. This reference design provides a high-precision, low-power, small-footprint solution for monitoring SpO2 levels using red and IR _LEDs . The MAX30102 module can realize pulse oximetry and heart rate monitoring. It integrates LED, photoelectric detection circuit, and optical components, and provides ambient light suppression to achieve low-noise detection of blood oxygen and heart rate signals. MAXREFDES1043 provides a complete system solution to simplify the design of mobile and wearable devices.
