This document proposes a design for an inexpensive, robust wind meter that uses four main components: 1) an inexpensive turbine, 2) weather protection casing, 3) small pager motor generator, and 4) single-chip microcontroller. The total cost would be around $0.50. Specific suppliers and part numbers are provided for prototyping the design, which involves 3D printing the turbine casing, sourcing the pager motor, and using an ATmel TinyAVR microcontroller to measure and output wind speed data from the generator. Code examples and links are given to test and implement the proposed low-cost wind meter solution.

1. INNOCENTIVE
SOLUTION
WIND METER

2. THE SUGGESTED SOLUTION
ONLY HAS ABOUT 4 PARTS
1. INEXPENSIVE PARTS
2. ROBUST
3. COST-EFFECTIVE TO MANUFACTURE
4. FLEXIBLE
5. POWERED BY THE WIND, NO BATTERY
TOTAL COST OF GODS IS AROUND 0.5$

3. SUGGESTED SOLUTION
● TURBINE
● WEATHER
PROTECTION
● GENERATOR
● ONE-CHIP
COMPUTER
● OUTGOING
SENSOR WIRES
● END COVER

4. GENERATOR
THE GENERATOR IS A PAGER MOTOR FOR GADGETS
SUCH AS PAGERS, MOBILE PHONES ETC.
IT COST AROUND 30 CENT IN LARGER VOLUMES
[WE HAVE EXTENSIVE EXPERIENCE WITH THIS MOTOR BOTH USED AS ENGINE AND AS
GENERATOR, IT WOULD FIT THIS APPLICATION EXCELLENTLY]----EXAMPLE SUPPLIER:
