According to datasheet:
Pin1, black -> arduino(common) GND
Pin2, red -> external power 7V..12V
Pin3, white -> arduino analog pin
Pin4/5, ora/yel -> any arduino digtal pins (avoid pins 0/1 as they are used for your USB-interface)
Use softwareserial (or altsoftserial) for the software UART
Read the analog input. Tha value (0V..4V) is proportional to wind speed.
for serial comm, see the manual
