The MAX30102 is an integrated pulse oximetry and heart-rate monitor biosensor module that includes:
- Two LEDs (Red and IR)
- Photodetector
- Optimized optics
- Low-noise analog signal processing
Key features:
-
Main functions:
- Heart rate monitoring
- Blood oxygen saturation (SpO2) measurement
-
Technical specifications:
- Operates on 1.8V and 3.3V
- I2C digital interface
- Integrated ambient light rejection
- Ultra-low power operation
- Programmable sample rate
-
Common applications:
- Wearable devices
- Fitness trackers
- Medical monitoring devices
- Mobile devices
The main difference from the MAX30105 is that the MAX30102 lacks the green LED and is specifically optimized for pulse oximetry and heart rate monitoring, while not including particle sensing capabilities.
