 This is a maintained version of the [original DFRobot_mmWave_Radar](https://github.com/DFRobotdl/DFRobot_mmWave_Radar) library.  After more than two years had passed without any commits beyond the initial commit, and issues receiving no attention, I assumed that it had become abandonware, so decided to fork this library to bring it up-to-date and get it published into the Arduino Library and PlatformIO Registry.
