Abstract

Construction panels and other materials, methods for their manufacture, and systems and methods for monitoring environmental conditions with such panels are provided herein. The panels include at least one environmental sensor assembly associated with a panel core and configured to detect an environmental condition of the panel comprising moisture, pressure, or both, and wirelessly communicate data on the environmental condition to a reader.

First claim

What is claimed is:

1. A building panel, comprising:
a panel comprising a panel core and having a first surface and an opposed second surface; and
at least one environmental sensor assembly associated with the panel core and configured to detect an environmental condition of the panel comprising moisture, pressure, or both, and wirelessly communicate data on the environmental condition to a reader,
wherein the at least one environmental sensor assembly is self-supporting, passive, and comprises an antenna, a processing module, and a wireless communication module, and
wherein the at least one environmental sensor assembly is disposed between layers forming the panel core, or disposed between the first surface of the panel core and a panel facing material.

2. The building panel of claim 1 , wherein the panel core comprises a gypsum panel core.

3. The building panel of claim 2 , wherein:
the gypsum panel core comprises a first gypsum layer and a second gypsum layer, the first gypsum layer comprising a slate coat layer, and
the at least one environmental sensor assembly is disposed between the first and second gypsum layers.

4. The building panel of claim 3 , wherein the first gypsum layer is present in an amount from about 2 percent to about 20 percent, by weight, of the gypsum panel core.

5. The building panel of claim 2 , wherein:
the panel further comprises the panel facing material, which comprises a fiberglass facing mat, and
the at least one environmental sensor assembly is disposed between the first surface of the panel core and the fiberglass facing mat.

6. The panel of claim 1 , wherein the at least one environmental sensor assembly comprises a passive radio frequency identification sensor.

7. A system for detecting an environmental condition at a panel, comprising:
at least one of the building panels of claim 1 ; and
at least one reader for receiving the data wirelessly communicated from the at least one environmental sensor assembly.

8. The system of claim 7 , further comprising a processing unit, wherein the reader is configured to communicate the data on the environmental condition to the processing unit, and the processing unit is operable to determine at least one condition status at the at least one environmental sensor assembly from the data.

9. The system of claim 7 , wherein the at least one reader comprises a stationary powered reader positioned at or near the least one building panel or a handheld manual reader.

10. A method of detecting an environmental condition, comprising:
providing at least one of the building panels of claim 1 ; and
wirelessly communicating data on the environmental condition from the at least one environmental sensor assembly to a reader.

11. The method of claim 10 , further comprising:
communicating the data on the environmental condition to a processing unit; and
determining, at the processing unit, at least one condition status at the at least one environmental sensor assembly.

12. The method of claim 10 , wherein the environmental condition comprises moisture.

13. A method, comprising:
the method of claim 12 ; and
repairing the building panel or a portion of the building panel at which a moisture condition is detected.

14. The method of claim 13 , further comprising identifying the portion of the building panel at which the moisture condition is detected by locating at least one visual indicator positioned on an external surface of the panel, each of the at least one visual indicators indicating a location of an environmental sensor assembly within the building panel.

15. The method of claim 14 , wherein the at least one visual indicator comprises a score or mark.

16. A building panel, comprising:
a panel comprising a panel core and having a first surface and an opposed second surface; and
at least one environmental sensor assembly associated with the panel core and configured to detect an environmental condition of the panel comprising moisture, pressure, or both, and wirelessly communicate data on the environmental condition to a reader,
wherein the at least one environmental sensor assembly is self-supporting, passive, and comprises an antenna, a processing module, and a wireless communication module, and wherein:
the panel comprises a first external surface and an opposed second external surface, and
the building panel further comprises at least one visual indicator positioned on the first external surface of the panel, each of the at least one visual indicators indicating a location of each of the at least one environmental sensor assemblies.

17. The building panel of claim 16 , wherein the at least one visual indicator comprises a score or mark.

18. A building panel, comprising:
a panel comprising a panel core and having a first surface and an opposed second surface; and
at least one environmental sensor assembly associated with the panel core and configured to detect an environmental condition of the panel comprising moisture, pressure, or both, and wirelessly communicate data on the environmental condition to a reader,
wherein the at least one environmental sensor assembly is self-supporting, passive, and comprises an antenna, a processing module, and a wireless communication module, and
wherein the at least one environmental sensor assembly comprises a plurality of environmental sensor assemblies spaced from one another at a distance of from about 1 foot to about 4 feet.

19. A method of manufacturing a building panel, comprising:
combining a panel core slurry and a panel facing material to form a panel core having a first surface and an opposed second surface, the first surface being associated with the panel facing material; and
disposing at least one environmental sensor assembly within the panel core slurry or between the panel core slurry and the panel facing material, such that the at least one environmental sensor assembly is disposed between layers forming the panel core, or disposed between the first surface of the panel core and the panel facing material,
wherein the at least one environmental sensor is configured to detect an environmental condition of the panel comprising moisture, pressure, or both, and wirelessly communicate data on the environmental condition to a reader,
wherein the at least one environmental sensor assembly is self-supporting, passive, and comprises an antenna, a processing module, and a wireless communication module.
