MAX30102 Heart Rate and Pulse Oximeter Sensor Features: Optical Heart-Rate Monitor and Pulse Oximetry Solution Upgraded version of MAX30100, the MAX30102 has better accuracy and reliability and some new features. New features include : Proximity sensing, and better ambient light cancellation. Tiny breakout board Low power Highly-integrated, small-size sensor Non-chest based heart-rate/SpO2 detection Ultra-low power consumption Specifications: Power supply: 3.3V to 5.5V Current draw: ~600μA (during measurements), Current draw: ~0.7μA (during standby mode) Red LED Wavelength: 660nm IR LED Wavelength: 880nm Temperature Range: -40˚C to +85˚C Temperature Accuracy: ±1˚C Pin Configuration: VIN is the power pin. You can connect it to 3.3V or 5V output from your Arduino. SCL is the I2C clock pin, connect to your Arduino’s I2C clock line. SDA is the I2C data pin, connect to your Arduino’s I2C data line. INT The MAX30102 can be programmed to generate an interrupt for each pulse. This line is open-drain, so it is pulled HIGH by the onboard resistor. When an interrupt occurs the INT pin goes LOW and stays LOW until the interrupt is cleared. IRD The MAX30102 integrates an LED driver to drive LED pulses for SpO2 and HR measurements. Use this if you want to drive the IR LED yourself, otherwise leave it unconnected. RD pin is similar to the IRD pin, but is used to drive the Red LED. If you don’t want to drive the red LED yourself, leave it unconnected. GND is the ground. Applications: Fitness Assistant Devices Medical Monitoring Devices Home Heart Rate and SpO2 Monitoring

MAX30102 Heart Rate Sensor – Pulse Oximeter Module (Purple PCB) ✍️ Introduction Build reliable PPG projects faster with the MAX30102 heart rate sensor —an all-in-one pulse-oximetry front end that integrates red (≈660 nm) + IR (≈880 nm) LEDs , photodiode, low-noise AFE, and an I²C digital interface. A built-in 32-sample FIFO smooths reads, while adjustable LED current (0–50 mA) and pulse width (69–411 µs) help you balance signal quality vs. power. Programmable output rates from 50 to 3200 samples/s give you headroom from low-power wearables to lab demos. 📦 What’s Included MAX30102 pulse-oximetry / heart-rate sensor module (Purple PCB) × 1 ✨ Key Features Integrated PPG engine: red + IR emitters, photodiode, AFE, ADC, and ambient-light cancellation (ALC). ALC rejects up to 200 µA of ambient current for cleaner signals. I²C control + interrupt: standard I²C with INT pin for efficient reads; default slave ID 0b1010111 (0x57) . On-board FIFO: 32-deep buffer reduces MCU servicing overhead during continuous sampling. Tunable performance: 0–50 mA LED current and 69–411 µs pulse widths for HR/SpO₂ optimization. Flexible data rates: 50–3200 sps output data rate via registers. Die temperature readout: on-chip sensor with 0.0625 °C resolution for compensation. 📊 Specifications (from datasheet) Parameter Value / Notes Measurement principle Photoplethysmography (PPG) for HR / SpO₂ basis. LED wavelengths Red ≈ 660 nm , IR ≈ 880 nm . Output data rate 50–3200 sps programmable. LED current range 0–50 mA programmable. Pulse width options 69/118/215/411 µs . FIFO depth 32 samples . I²C address (7-bit) 0x57 (fixed slave ID bits 1010111 ). Supplies 1.8 V core ( VDD ) + separate 3.3 V LED supply ( VLED+ ). Temperature sensor resolution 0.0625 °C . Pins (module-level) VDD, GND, VLED+ , SDA, SCL, INT , PGND; N.C. pads for stability. Power note: Power VDD (1.8 V) first, then LED supply ( VLED+ ); I²C/INT pull-ups may be present even before power is applied. 🧰 Compatibility & Tips Seat the sensing window flush to skin with gentle pressure to reduce motion artifacts. Add pull-ups on SDA/SCL and a 0.1 µF decoupling capacitor near VDD . Start with moderate LED current and pulse width; then tune for your mechanical setup and environment. Apply digital filtering (e.g., band-pass around heart-rate band) and average multiple beats for stable readings. 🎯 Use Cases Wearables & fitness indicators • SpO₂-style demos • Sleep/relaxation monitors • Biomedical signal-processing labs 🛡️ Safety & Handling For development/education , not a medical diagnostic device. Avoid direct viewing of active LEDs at close range. Handle with ESD care; keep the sensor window clean. 📎 Media & Downloads Datasheet – MAX30102 (/Maxim Integrated) . 🚚 Quality, Shipping & Batch Notes Visual inspection for lens alignment and solder integrity before dispatch. Minor PCB/silkscreen variations may occur between batches without affecting function. Anti-static packaging to protect the sensor window. ❓ FAQ Q1: What is the default I²C address? A: 0x57 (slave ID bits 1010111). Q2: Which supplies are required? A: 1.8 V for the IC core ( VDD ) and a separate 3.3 V rail for VLED+ (LEDs). Q3: How do I reduce ambient light issues?
