Description:

The MAX30102 Sensor Module is a compact, high-performance, and power-efficient biosensing solution that integrates advanced optics and signal processing to measure two key health metrics: heart rate (pulse) and blood oxygen saturation (SpO₂). Based on the industry-leading MAX30102 IC from Maxim Integrated, this module combines red and infrared LEDs, a high-sensitivity photodetector, optical components, and low-noise electronics into a single module designed for accurate biometric detection.

Designed specifically for health-monitoring and wearable applications, the MAX30102 provides reliable real-time readings using photoplethysmography (PPG), a technique that uses light absorption by blood vessels under the skin to detect changes in blood volume.

Whether you're building a fitness band, developing a home-care medical device, or experimenting with human physiology in an IoT project, the MAX30102 is a powerful, compact, and easy-to-use sensor that brings professional-level biometric tracking to makers and engineers.
