Gravity: MAX30102 PPG Heart Rate and Oximeter Sensor (I2C/UART) ESP32-H2 This is an NFC-powered moduleDFRobot Gravity: MAX30102 heart rate and blood oxygen sensor module integrates the Maxim MAX30102 chip and an MCU with heart rate and blood oxygen algorithm. The MAX30102 uses PPG(PhotoPlethysmoGraphy) to measure data, which will be converted into heart rate and oximetry values when processed by the MCU, then output through I2C or UART, making the sensor easy to use and greatly reducing resource occupation of the main controller.
