Fermion: MAX30102 PPG Heart Rate and Oximeter Sensor (Breakout, I2C/UART) Laser Sensor 170×320 resolutionThe DFRobot heart rate and oximeter sensor integrates the Maxim MAX30102 chip and an MCU with heart rate and oximetry 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 main controller. Meanwhile, the corresponding upper computer is
