Description
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?

Description
Max30102 is an improved design version of better accuracy compared to Max 30100 pulse oximeter . The MAX30102 can be used as an oximeter by measuring the oxygen concentration in the blood (SpO2 percentage) and also can be used as heart rate sensor (beats per minute). The device has two LEDs, one emitting red light, another emitting infrared light. For pulse rate, only the infrared light is needed. Both the red light and infrared light is used to measure oxygen levels in the blood. How does the max 30102 pulse oximeter work? When the heart pumps blood, there is an increase in oxygenated blood as a result of having more blood. As the heart relaxes, the volume of oxygenated blood also decreases. By knowing the time between the increase and decrease of oxygenated blood, the pulse rate is determined. It turns out, oxygenated blood absorbs more infrared light and passes more red light while deoxygenated blood absorbs red light and passes more infrared light. This is the main function of the MAX30102: it reads the absorption levels for both light sources and store them in a buffer that can be read via I2C. Features Working voltage: 5V Integrates both complete pulse oximeter and heart rate sensor . Easy-to-use I2C interface. MAX30102 heart rate and pulse oximeter sensor datasheet
