Weather Sensors Installation
Proper siting for weather sensors is important to ensure accurate readings.  For example, wind sensors should not be installed too close to a building, as turbulence created by the building can interfere with readings.  The Solar Radiation sensor should be installed in direct sunlight on a level surface (bubble level and leveling screws are included with purchase).

Purchase of both the Wind Direction and Wind Speed sensors includes a T-mounting bar with a 1" stainless steel coupling unit and allen wrench for easy allen set screw instalation.  Individual wind sensors or solar radiation sensors include 1 inch stainless steel elbow couplers and an allen wrench.  The Solar Shield (with a stainless steel elbow coupler) can be used for protection and easy installation of the Temperature and Humidity sensors.  The Barometric Pressure sensor can be mounted with straps for a variety of applications (including inside a datalogger or to a display for hand-held use).
