MAX30100 / 30102 Heart Rate and Oxygen Pulse Sensor :

The MAX30100 and MAX30102 sensor modules are integrated solutions for heart rate and SpO? (oxygen saturation) monitoring, combining two key health parameters into one compact, easy-to-use unit. Designed by Maxim Integrated, these sensors use photoplethysmography (PPG) to detect blood volume changes in the microvascular bed of tissue.

These modules are perfect for wearable devices, DIY health monitors, or any embedded system requiring real-time health vitals.

Whether you're building a smart fitness band, remote health monitor, or IoT-based biofeedback system, Robo Pixel ensures you get high-quality modules that are reliable, tested, and fully supported.

Applications:

• DIY Health Monitoring Systems

• Fitness and Wearable Devices

• Smart Watches and Bands

• Biomedical and IoT Projects

• Student and Academic Research

How It Works

The MAX30100/30102 sensor uses two LEDs (red and infrared) and a photodetector to shine light through your skin (typically a finger or earlobe) and measure how much light is absorbed. This allows it to calculate:

• Heart Rate – Based on the pulse waveform (changes in blood flow)

• Oxygen Saturation (SpO?) – Based on the absorption ratio of red and infrared light

The data is digitized and transmitted via the I2C protocol, making it simple to interface with most microcontrollers.
