The UN03 shield is designed to protect your outdoor sensor from direct sunlight, rain, and other environmental elements, ensuring more accurate readings and extending sensor life.

1. Choose a Location: Select a location outdoors that is representative of the general outdoor conditions, away from direct sunlight, heat sources, and heavy precipitation. The shield can be wall-mounted or placed on a flat surface.
2. Insert Sensor: Carefully place your wireless outdoor sensor inside the UN03 protection shield. Ensure it fits snugly and is positioned correctly.
3. Mounting (Wall-mounted):
   • Mark the desired mounting points on the wall using the shield's mounting holes as a guide.
   • Drill pilot holes if necessary.
   • Insert wall plugs into the drilled holes.
