The MAX30102 3.3 to 5V Pulse Oximeter & Heart Rate Sensor Module (Black) is an integrated biosensor module designed for heart rate and blood oxygen (SpO₂) monitoring in electronic and wearable projects. It combines red and infrared LEDs, a photodetector, optical components, and low-noise circuitry with ambient light suppression to provide reliable readings.
The module communicates through a standard I2C interface, making it easy to connect with Arduino, ESP32, KL25Z, and other compatible microcontrollers for developing pulse oximeters, fitness monitors, wearable devices, and health-monitoring prototypes.
Its glass cover helps reduce unwanted light interference, while software shutdown keeps standby current close to zero, making the MAX30102 sensor module a practical choice for compact and low-power biometric sensing applications.
