  • Updates:
    • Conducted tests to verify that the real-time processing algorithm works
      • Tested algorithm at different fan settings
    • Documented the testing procedure
  • To Do:
    • Adjust code to measure wind speed and direction using four microphones
      • Have microphones facing 90 degrees to each other and develop an algorithm to calculate the angle
      • Have center microphone be the base of 0 degrees
  • Updates:
    • Worked on the actual algorithm for deriving time.
      • Attempted to get the propagation time between 2 microphones using the start and end times. However, there was a big difference between the propagation time as measured by the differences in the start, and the time measured by the end. Upon further observation we determined that the second microphone is taking longer to measure 1000 cycles, which may mean that not all the waves are reaching it. We then thought to compare the differences between each wave instead of just the start and end.
      • We're working on saving the data into an array so we can check for and filter out erroneous data.
  • To Do:
    • Finish up the data comparisons using the array and test with a lot of samples to get a good result.
