Description: MAX30102 Pulse Oximeter Heart Rate Sensor Module: 1. Pulse Oximetry Sensing: Maxim Integrated's MAX30102 is a compact, high-performance sensor module for noninvasive measurement of both heart rate (HR) and blood oxygen saturation (SpO2). 2. Easy Interfacing: Features an I²C interface for simple integration with microcontrollers and other devices, requiring minimal external components. 3. Low Power Consumption: Operates at 1.8V to 5.5V DC and draws less than 2 mA of current during operation, making it suitable for battery-powered applications. 4. LEDs for Heart Rate Detection: Includes red and infrared LEDs along with photodiodes, enabling accurate HR detection through the plethysmographic effect. 5. SpO2 Measurement: Uses the proprietary Signal Multiplexing System to provide high-resolution SpO2 readings with minimal interference from ambient light. 6. Adaptive Calibration: Includes self-calibrating features that minimize the need for manual calibration, ensuring accurate and consist
