BASICS
 Ensure the sensor is mounted level with the Solar Panel facing
directly to the south. This will help optimize battery life and transmit
correct wind direction readings.
 Ideally, the Breeze Pro Sensor should be mounted on the tallest
object in your area. Avoid positioning the sensor in line with or
below eaves, rooflines, trees, or other objects that may obstruct
wind readings.
 Make sure all screws on the Mounting Bracket, Winds Cup, Wind
Vane, and Battery Compartment are securely fastened.
 The sensor should be mounted with the Wind Cups on top.
 The Breeze Pro sensor has a transmission range of 330 feet from
sensor to display.

Basic Installation Options
1A Adjustable Base
1B Pole Adapter
Fence posts, poles, decks, and even mailboxes are all common mounting options due to their
convenience. Many users prefer these types of locations as the data they provide is accurate from their
ground level perspective. However, because wind in these spots is often aected by obstructions, the
readings may dier compared to local reporting stations.
1A. Mount the Adjustable Base onto a flat surface using the four provided
screws.
1B. Secure the Pole Adapter to a cylindrical conduit using the two
provided screws.
2. Insert the Mast into the Breeze Pro Sensor and tighten the provided
screws on the sides.
3. Use the Hand Screw to attach the Mast to either the Adjustable Base
or Pole Adapter. Ensure the sensor is level, facing south, and securely
fastened at all mounting points.
Advanced Installation Options
Some advanced installation options include tripods, wall mounts, eave cross mounts, chimney mounts,
and many others. Any of these can be combined with U-bolts for attachment onto a tall cylindrical
conduit using our Adjustable Base. Please note that these advanced options will require additional
equipment and possibly professional help for best results.
