Project Objectives
High Priority Objectives
User-defined wind-speed setting for shutoff
User-defined wind-speed setting for reset (should not be the same as shutoff to avoid cycling)
Accuracy of measuring wind-speed
Manual override to allow user to override the sensor when desired
Second Priority Objectives
Durable/UV resistant to last for a 5 year warranty
Electrical Reliability
Cost efficiency
Environmental Performance – related to outdoor factors (sunlight, insects, humidity, etc.)
Other Constraints and Issues
Operational Temperature Range (0-140 degrees Fahrenheit)
Structural Integrity/Mountability
Ease of Assembly
Ease of Installation
Ease of use
Ease of replacement
Use of hardware for maintenance requiring only common hand tool
WOW Design Solution
· The WOW design is up to the students… not to be limited by constraints or the pre-existing Wind-Clik design.
Risk Reduction Strategy
It is important for the sensor to not stop working, and for the wind-speed measuring device to be accurate. The sensor has to be reliable and nearly maintenance-free. The system cycling between shutoff/reset needs to be avoided. Possible tests include: anemometer for accuracy in measuring wind-speed, and durability of electrical switches. Durability of hardware in outdoor environment. If microcontroller used, test overheating possibilities. Primary testing will take place after prototype is delivered.
Intermediate Milestones
A well defined schedule using Microsoft Project
Create a reliable AC motor/signal
Determine the wind speed and voltage relationship
Create CAD drawings of all components and assemble
Build a Prototype
