Unlock Vital Biometric Data with the GY-MAX30100 Sensor Module

The GY-MAX30100 is a compact and powerful optical sensor module designed to accurately measure heart rate and blood oxygen saturation (SpO2). Perfect for makers, developers, and educational projects, this module provides reliable biometric data, making it an essential component for wearable health devices, fitness trackers, and various health monitoring applications.

How It Works:

This innovative module utilizes Maxim's MAX30100 integrated sensor. It employs an advanced optical sensing method:

• Dual-Wavelength LEDs: Emits both red and infrared light.
• Photodetector: Measures the light absorbed by pulsing blood through a fingertip.
• Optimized Design: Specifically engineered for accurate readings when placed on the tip of a finger.
• Low-Noise Signal Processing: An integrated analog signal processing unit ensures clean and precise data.

Key Features:

• Integrated Optical Sensor: Combines IR and red LEDs with a sensitive photodetector for robust measurements.
• Measures Pulsing Blood Absorbance: Advanced technology for accurate heart rate and blood oxygen data.
• I2C Communication Protocol: Easy integration with microcontrollers (MCUs) using the standard I2C interface.
• Programmable INT Pin: Provides interrupt functionality for event-driven applications.
• Wide Power Supply Compatibility: Operates on 3V to 5V power supplies, offering flexibility.
• Compact Size: At just 14mm x 14mm, it's ideal for space-constrained projects.

Key Benefits:

• Motion Artifact Resilience: Designed to provide more stable readings even with slight movement.
• Ambient Light Cancellation: Minimizes interference from surrounding light sources for consistent data.
• Simplified Development: Ready-to-use examples and support in MikroElektronika compilers save valuable development time.
• Versatile Applications: Ideal for developing algorithms for pulse oximetry and heart rate readings.

Important Considerations for Optimal Readings:

• Avoid excessive motion during measurements.
• Maintain a stable temperature for the best results.
• Apply gentle pressure; too much pressure can restrict blood flow and affect accuracy.

Technical Specifications:

• Supply Voltage: 3V - 5V
• Dimensions: 14mm x 14mm
• Communication: I2C Protocol
• Power Supply: Uses 3.3V (internal operation)
