Wind Direction Sensor - RS485 Output
Easily measure wind direction with this sensor from PMD Way.
This sensor outputs an RS485 modbus signal that is relevant to the direction. Your microcontroller or other device needs an RS485 interface.
Direction is calculated as 4mA for zero degrees, then 1mA for each of sixteen directions.
Operating voltage: 7~24V DC. Includes 1m cable as shown in image.
