Description

High-Precision MAX30102 Sensor Module for Health Monitoring

Technical Specifications of MAX30102 Sensor Module

• Detection Type: Advanced optical reflection signal (PPG) for non-invasive pulse and blood oxygen sensing.

• Dual Wavelengths: Integrated Red LED (660nm) and Infrared LED (880nm) for SpO2 calculation.

• ADC Resolution: Built-in 18-bit analog-to-digital converter for high-fidelity physiological data acquisition.

• Interface: Industry-standard I2C communication protocol for seamless integration with modern microcontrollers.

• Supply Voltage: Flexible VIN input range from 1.8V to 5V with on-board regulators.

• Current Consumption: Ultra-low operating current below 600µA and 0.7µA in standby mode.

• Ambient Rejection: Sophisticated internal circuitry effectively minimizes interference from external light sources.

• Temperature Sensor: On-chip die temperature sensor provides internal compensation for data accuracy.

• Form Factor: Tiny 14-pin optical module with an integrated cover glass for durability.

Usage and Biomedical Integration

• First, connect the VCC and GND pins to a stable 3.3V or 5V power source.

• Next, link the SDA and SCL lines to your Arduino’s I2C hardware pins.

• Then, install a compatible MAX3010x library to handle the complex mathematical SpO2 algorithms.

• Afterward, place your fingertip lightly on the glass surface for consistent PPG signal detection.

• Consequently, the MAX30102 Sensor Module transmits raw red and IR data for real-time analysis.

• Finally, visualize heart rate and oxygen levels on a serial plotter or OLED display.

Advantages and Disadvantages of MAX30102 Sensor Module

• Pros: Highly integrated design combines LEDs and photodetectors into a single wearable-ready footprint.

• Furthermore, the ultra-low power consumption makes it ideal for battery-operated fitness tracking projects.

• Cons: Raw data requires significant software processing to filter out motion artifacts and noise.

• Additionally, excessive pressure from the finger can temporarily restrict blood flow and distort readings.

Precautions and Handling Advice

• Warning: Do not apply excessive mechanical pressure to the sensor’s delicate glass cover.

• Avoid exposing the module to direct sunlight during measurements to prevent ambient light saturation.

• Ensure the I2C pull-up resistors match your microcontroller’s logic level (1.8V vs 3.3V).

What is Included in the Package

• 1x MAX30102 Sensor Module with pre-soldered optical components.

• 1x 7-Pin male header strip for easy breadboard prototyping and wiring
