MAX30102 3.3 to 5V Pulse Oximeter & Heart Rate Sensor Module (Black)
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.
Features:
- Measures heart rate and blood oxygen (SpO₂) using red and infrared LEDs.
- Built-in photodetector and ambient light suppression for reliable sensing.
- Standard I2C interface for easy connection with Arduino, ESP32, and other microcontrollers.
- Supports low-power operation with software shutdown and near-zero standby current.
- Ideal for wearable devices, health-monitoring, IoT, and DIY pulse oximeter projects.
