Inspeed Wind Direction Sensor

Has anyone set this sensor up? I'd like to be able to measure wind speed while driving, and I'll need the wind direction to do that. That sensor does not include any adapters or connectors, and requires 5V DC power. I'd like to power and read it with a USB module. Stuart Robinson posted a device like that in a previous thread: http://www.pc-control.co.uk/wasp_info.htm However, in the schematic they show an external power source. Does anyone know of something similar I can power through the USB?

To measure windspeed while driving can't you just subtract your vehicle speed from what the sensor reads? While driving I'd assume your direction would be the direction your car is headed so I'm not sure how that would aid in wind speed.

That only works if you are driving directly into the wind or directly with the wind. Otherwise, the component of the wind that is perpendicular to your direction of travel will throw your reading off.

I think that if you have a reading for wind direction you can do a vector substraction and you will get somehow a valid wind speed and wind direction....


But you'll need a perfect installation and somehow perfect equipment...
