Calculation Formula
Voltage type (0～5V output)： D = 360°×V / 5 ( D: indicating value of wind direction，V: output-voltage(V)) Current type ( 4～20mA output )： D=360°× ( I-4 ) / 16 ( D indicating value of wind direction，I: output-current (mA)) Wiring Method There is three-core aviation plug, whose output is at the base of the sensor. The definition of each pin’s corresponding base pin.
（1）If you have equipped with our company’s weather station，please attach the sensor cable to the appropriate connector on the weather station directly. （2）If you purchase the sensor separately, the order of the wires are as followed: R(Red)：Power ＋ Y(Yellow)：Signal output G(Green)：Power — （3）Two ways of wiring method of pulse voltage and current:
