## Description

The MAX30102 is an integrated heart rate and pulse oximetry (SpO2) sensor module. It combines red and infrared LEDs, a photodetector, and low-noise analogue electronics in a single package, communicating over I²C. Ideal for wearable health monitors, fitness trackers, and biomedical prototyping. The module accepts 3.3–5 V input and draws a maximum of 6 mA. A software-controlled shutdown mode reduces standby current to near zero, making it well-suited for battery-powered applications. Key Features Heart Rate + SpO2 – Measures pulse and blood oxygen saturation via PPG Dual-Wavelength LEDs – 660 nm (red) and 880 nm (IR) for accurate readings 18-Bit ADC – High-resolution analogue-to-digital conversion Adjustable Sampling Rate – 50 Hz to 3200 Hz I²C Interface – Standard two-wire connection to any microcontroller Low Power – 6 mA max; software shutdown for near-zero standby Interrupt Pin – Hardware interrupt for real-time event notification Specifications Sensor: Maxim MAX30102 Input Voltage: 1.8–5 V DC Current Draw: 6 mA max ADC Resolution: 18-bit LED Wavelengths: 660 nm / 880 nm Sampling Rate: 50–3200 Hz Operating Temperature: −40 to +85 °C Interface: I²C Pinout VIN – Power input (1.8–5 V DC) SCL / SDA – I²C clock and data INT – Interrupt output RD / IRD – Ground for red and IR LEDs GND – Common ground Ideal For Wearable fitness and health monitors Biomedical and SpO2 prototyping Arduino and Raspberry Pi health-sensing projects Package Contents 1× MAX30102 Heart Rate and Pulse Oximeter Sensor Module
