Sensors ordered from Seeedstudio

Just placed an order from a china based Arduino supplier Seeedstudio. If the name means something I haven't figured it out yet...

• I'll use the UNO to test and work out the code.
• The Photo interrupter is a photogate that I hope to use to build a paddlewheel type speedometer.
• The Photo Reflective Sensor will be used for the Anemometer (hand drawn design to follow).
• I'm going to attach the piezo sensor (vibration sensor) to a tell tale and glue one to each side of the main sail. That will (hopefully) tell me if I have laminar flow across each side of my sail.

1 x Arduino UNO (ARD132D2P) = $29.90
