This is an assembly designed to provide a fan aspirated flow of ambient air over a weather station temperature and humidity sensor assembly mounted outside on a pole or similar support. There are three different configurations provided with a separate Bill of Materials (BOM) (parts list for each. The configurations include a design that is intended to be mounted on a 1 inch OD pole (3/4" Schedule 40 PVC pipe), a bottom mounted 90 degree bracket, and a top mounted 90 degree bracket. The design uses a commonly available 40 X 40 X 20 mm 12 volt DC fan for air circulation (different voltages and airflow rating may be procured depending on the application. Many of the parts are common to all three configurations. Currently the screens are in use with a WiFi weather station from: https://wunderweatherstation.wordpress.com/
