Weather is one of the most important factors for human and life and food security, and wind speed is one of the elements to measure in weather stations. This is a wind speed detector or a.k.a anemometer. It is portable, easy to carry and assembly, made of polycarbon which is anti-corrosion rust at the same time to overcome the ABS plastic aging problems. The bottom outlet and the outlet side of the equipment are compatible with each other. Interface/Output: RS485 communication (modbus) protocol Baud rate: 2400, 4800 (default), 9600 Data bit length: 8 bits Parity check method: None Alternative Interface/Output: 5-420MA Application: Measurement of Horizontal Wind Velocity at Near-Surface Layer of Port Meteorological environment Airport Expressway Monitoring Agriculture and forestry, environmental protection industry This is an example schematic diagram for the connection between NPN Anemometer and Arduino. This connection requires a pull-up resistor to logic voltage, recommended to use a 5.1k Ohm resistor.
