Images are for illustration purposes only. E&OE Overview The wind speed sensor is composed of a shell, three wind cups and a circuit module, which is made of aluminum alloy material. The whole sensor has a high strength, weather resistance, corrosion resistance and water resistance, will be to ensure the long-term use of the instrument, and the accuracy of the wind speed collection.It is very suitable for outside measurement. Features Small size, aluminum alloy material, high strength Exquisite appearance, high precision measurement Long signal transmission distance, strong anti-interference ability Low power consumption, Wide range, good data information Easy to installation , easy to carryThe unit uses +12 to 24 V and gives an output of 4 - 20mA If you want to connect it to a microcontroller you need to connect a resistor between the signal out and ground to get a voltage out. If you use a 250R resistor it will give 1 to 5V out to use with a microcontroller. According to the datasheet the windspeed will be 0 to 30 m/s for the 4 - 20 mA output, thus with the resistor it will be 1-5V for 0 - 30m/s wind.
