Attended: Daisy, Mengyuan, Creighton, Scott

• Collected raw data from teensy with one microphone
  • Plotted data in excel to gain an understanding of the data we are working with
  • Tests conducted in multiple conditions:
    • sound frequencies of 2k, 4k, 6k, 10k, 12k, and 14k Hz
    • indoors with Vornado fan at highest speed setting
• Received Omega HHF802 Anemometer this week
  • Difficulty connecting anemometer to Matlab via RS232 data cable
    • Matlab sees device in serial port but gives the error: “the specified amount of data was not returned within the timeout period”
• Other possible wind sensor ideas
  • Ultrasonic sensor
    • Measure the time it takes for sound to travel from emitter to receiver
    • Use equation for wind speed that takes into account temperature, pressure, humidity, etc.

• To Do:
  • Consider splitting up into two groups:
    • Mengyuan to research ultrasonic wind sensor
    • Creighton and Scott to continue replicating Andy's tests and results to gain further understanding
  • Etch/mill working board by the end of the semester
