Code Examples:

The provided code examples demonstrate how to integrate the MAX30102 with an Arduino or compatible microcontroller. Here’s a summary of the two examples:

First Code: Basic Heart Rate and SpO2 Measurement

This code reads data from the MAX30102 sensor and outputs the Infrared (IR) and Red values to the Serial Monitor. It’s designed to help you get started with the basic functionality of the sensor.

Key Steps:

1. Initialize the sensor: The sensor is initialized using the MAX30105 library and the I2C interface.

2. Set parameters like LED brightness, sample rate, and pulse width.

3. Monitor data: The sensor’s IR and Red readings are continuously checked, and their values are printed to the Serial Monitor.

Second Code: Optical Heart Rate Detection Using the PBA Algorithm

This code demonstrates the use of the PBA (Peripheral Beat Amplitude) Algorithm to detect heart rate using the MAX30105 sensor. The sensor detects beats and calculates beats per minute (BPM), showing the real-time heart rate of the user.

Key Steps:

1. Initialize the sensor: Set up the MAX30105 sensor and configure its LED and sampling settings.

2. Measure heart rate: The code detects heartbeats by monitoring the IR values and calculates BPM.

3. Display Results: The BPM value and the average BPM are printed to the Serial Monitor.

Applications:

• Health Monitoring Systems: Perfect for wearable health devices that track heart rate and SpO2.

• Fitness Trackers: Use in fitness bands or smartwatches to monitor users’ vital signs.

• Medical Devices: Can be integrated into clinical equipment to continuously monitor patients’ vital health metrics.

• DIY Projects: Great for DIY health tech projects, educational projects, and research.
