Gravity: MAX30102 PPG Heart Rate and Oximeter Sensor (I2C/UART)

The DFRobot Gravity: MAX30102 heart rate and blood oxygen sensor module is your go-to solution for measuring vital signs with precision. It incorporates the highly efficient Maxim MAX30102 chip alongside an MCU that is specialized in heart rate and blood oxygen algorithms. This efficient pairing ensures real-time and accurate data collection.

At the core of its functionality is the use of PhotoPlethysmoGraphy (PPG), a technique that captures the subtle changes in light absorption of blood as it pulses. This data is skillfully converted into readable heart rate and oximetry values by the onboard MCU, with seamless output available through I2C or UART interfaces. This feature makes the sensor incredibly accessible and minimizes the main controller's resource consumption.

A dedicated upper computer software provides effortless data access on your PC, allowing you to monitor your health metrics conveniently without any specialized tools. The module's practical design ensures varied applications—from integrating into wearable tech to enhancing DIY health monitoring systems. Keep in mind, proper attachment to your finger will yield the best readings, albeit not comparable to professional medical devices in diagnostic precision.
