MAX30102 Sensor

Description:

The MAX30102 Sensor Module is an advanced biometric sensor that integrates a pulse oximeter and heart-rate monitor in a compact package. It is the upgraded version of the MAX30100, offering better performance, lower power consumption, and improved ambient light rejection. This sensor uses two LEDs (red and infrared), a photodetector, and an analog front-end to measure blood oxygen saturation (SpO₂) and pulse rate through fingertips or earlobes. With an I2C interface, it’s easy to integrate with Arduino, Raspberry Pi, ESP32, and other microcontrollers. Ideal for wearable devices, health monitoring systems, and fitness applications.
