An inexpensive cup anemometer that updates data every five minute to a computer.
To add a little more challenge to this project and make it less expensive, I decided to try to build the anemometer using parts I already have, if possible. Here is a small list of parts:
- 3x plastic coffee spoons
- 1x coke cap
- 1x ‘pinch roller’ (from a VCR)
- 1x slotted infra-red sensor
- 1x aluminium stick
- 1x spray can cap
- 1x transistor
- 2x resistors
- 1x triple contact terminal block
