The MAX30102 Heart Rate Oxygen Pulse Breakout Sensor Module is an integrated pulse oximeter and heart-rate monitoring solution designed for wearable devices, fitness assistants, and medical monitoring applications. This optical sensor module features two LEDs—red and infrared—that emit wavelengths optimized for accurate readings through fingertip measurement. The module includes an integrated LED, photodetector, and high-performance analogue front-end, all housed on a compact breakout board. With a 16-bit sigma-delta ADC and 16-deep FIFO data storage, the MAX30102 delivers precise measurements whilst consuming ultra-low power, making it ideal for battery-operated systems. The module operates at 1.8V to 3.3V and communicates via I2C digital interface, allowing seamless integration with microcontrollers such as ESP8266, ESP32, and other development boards. It features ambient light cancellation and a proprietary discrete-time filter for enhanced accuracy. The device is fully configurable through software registers and can be powered down with negligible standby current. This sensor module is perfect for DIY electronics projects, IoT devices, fitness trackers, and educational experiments requiring heart rate and blood oxygen monitoring capabilities. 🔧 Technical Specifications Sensor IC: MAX30102 Measurements: Heart Rate & Blood Oxygen (SpO2) Interface: I2C Operating Voltage: 3.3V – 5V DC LED Type: Red & Infrared Low-Power Mode: Yes PCB Type: Breakout Sensor Board
