Wind Sensor Team Meeting- October 29, 2016
Attended: Mengyuan, Creighton, Scott
Updates
- Compared the fourier transform of the microphone readings at different fan settings
- Filtered out the DC component
- Determined that there isn't any useful information from just the fourier transform
- There's been some difficulty with implementing different Fourier analysis techniques, so this analysis will be put on hold.
- Found a hardware implementation for an interrupt which led to consistent measurements for counting clock cycles.
Reminders
- To Do:
- Replicate Andy's test and results with four microphones and in different environments by the end of this week
- Design a PCB by the end of this week
- Etch/mill PCB by the first week of November
- Test hardware interrupt implementation.
