Wind Sensor Team Meeting-January 27, 2017
Attended: Mengyuan, Creighton, Scott
Acoustic Wind Sensor
- Updates:
- To Do:
Ultrasonic Wind Sensor
- Updates:
- Continued researching methods of determining propagation time
- One method is to keep track of the start time (signal sent) and the end time (signal received)
- Because we don't have a transducer yet to keep track of the start, we will improvise with using two receivers and a source further away, the propagation time being the time between the receivers
- Started developing an algorithm and circuit to accomplish above
- The algorithm will use a combination of thresholding and phase shift detection to determine precisely the time
- Need a Schmitt trigger for counting the wavelength number
- Found a Schmitt trigger on DigiKey
- To Do:
- Update parts order list with Schmitt trigger
- Continue developing algorithm and circuit
