MAX30102 Pulse Oximeter Heart Rate Pulse Sensor Module

MAX30102 Pulse Oximeter Heart Rate Pulse Sensor Module.

The MAX30102 Pulse Oximeter and Heart Rate Pulse Sensor Module is an integrated sensor solution designed to measure heart rate and blood oxygen saturation (SpO?) levels accurately. It uses advanced optical technology with red and infrared LEDs along with a photodetector to sense variations in light absorption through blood vessels, which correspond to pulse and oxygen levels. The module is ideal for wearable health devices, fitness trackers, and biomedical monitoring projects.

It communicates easily with microcontrollers such as Arduino, ESP32, STM32, and Raspberry Pi using the I²C interface and operates efficiently on 3.3V to 5V power supply.
