Abstract

A method of tracking an indoor air quality (IAQ) level experienced by an individual including: detecting a first IAQ data set within a first room at a plurality of time increments using a first IAQ detector in the first room; determining a first IAQ health level for each of the plurality of time increments; detecting a second IAQ data set within a second room at the plurality of time increments using a second IAQ detector in the second room; determining a second IAQ health level for each of the plurality of time increments; detecting the individual being located within the first room during a first time period and within the second room during a second time period; and combining the first IAQ health level during the first time period and the second IAQ health level during the second time period into a true IAQ health level graph.

Claims (51)

1 . A method of tracking an indoor air quality (IAQ) level experienced by an individual, the method comprising:

detecting a first IAQ data set within a first room at a plurality of time increments using a first IAQ detector in the first room;

determining a first IAQ health level for each of the plurality of time increments based on the first IAQ data set;

detecting a second IAQ data set within a second room at the plurality of time increments using a second IAQ detector in the second room;

determining a second IAQ health level for each of the plurality of time increments based on the second IAQ data set;

detecting the individual being located within the first room during a first time period of the plurality of time increments;

detecting the individual being located within the second room during a second time period of the plurality of time increments;

extracting the first IAQ health level for each of the plurality of time increments during the first time period from the first IAQ health level for each of the plurality of time increments that was determined;

extracting the second IAQ health level for each of the plurality of time increments during the second time period from the second IAQ health level for each of the plurality of time increments that was determined; and

combining the first IAQ health level for each of the plurality of time increments during the first time period and the second IAQ health level for each of the plurality of time increments during the second time period into a true IAQ health level graph.

2 . The method of claim 1 , further comprising: displaying the true IAQ health level graph on a computing device of the individual.

3 . The method of claim 2 , further comprising: transmitting the true IAQ health level graph to the computing device of the individual.

4 . The method of claim 1 , wherein detecting the individual being located within the first room during the first time period of the plurality of time increments further comprises:

detecting wireless communication of a computing device of the individual using the first IAQ detector.

5 . The method of claim 4 , wherein the wireless communication is a Bluetooth signal.

6 . The method of claim 1 , wherein the first IAQ detector is located in a fire detector.

7 . An indoor air quality (IAQ) detector system having one or more IAQ detectors, the IAQ detector system comprising:

a processor; and

a memory comprising computer-executable instructions that, when executed by the processor, cause the processor to perform operations, the operations comprising:

detecting a first IAQ data set within a first room at a plurality of time increments using a first IAQ detector in the first room;

determining a first IAQ health level for each of the plurality of time increments based on the first IAQ data set;

detecting a second IAQ data set within a second room at the plurality of time increments using a second IAQ detector in the second room;

determining a second IAQ health level for each of the plurality of time increments based on the second IAQ data set;

detecting an individual being located within the first room during a first time period of the plurality of time increments;

detecting the individual being located within the second room during a second time period of the plurality of time increments;

extracting the first IAQ health level for each of the plurality of time increments during the first time period from the first IAQ health level for each of the plurality of time increments that was determined;

extracting the second IAQ health level for each of the plurality of time increments during the second time period from the second IAQ health level for each of the plurality of time increments that was determined; and

combining the first IAQ health level for each of the plurality of time increments during the first time period and the second IAQ health level for each of the plurality of time increments during the second time period into a true IAQ health level graph.

8 . The IAQ detector system of claim 7 , wherein the operations further comprise: displaying the true IAQ health level graph on a computing device of the individual.

9 . The IAQ detector system of claim 8 , wherein the operations further comprise: transmitting the true IAQ health level graph to the computing device of the individual.

10 . The IAQ detector system of claim 7 , wherein detecting the individual being located within the first room during the first time period of the plurality of time increments further comprises:

detecting wireless communication of a computing device of the individual using the first IAQ detector.

11 . The IAQ detector system of claim 10 , wherein the wireless communication is a Bluetooth signal.

12 . The IAQ detector system of claim 7 , wherein the first IAQ detector is located in a fire detector.

13 . The IAQ detector system of claim 7 , wherein the first IAQ detector detects one or more of particulate levels and carbon dioxide (CO2) levels.

14 . A non-transitory computer program product tangibly embodied on a non-transitory computer readable medium, the non-transitory computer program product including instructions that, when executed by a processor, cause the processor to perform operations comprising:

detecting a first IAQ data set within a first room at a plurality of time increments using a first IAQ detector in the first room;

determining a first IAQ health level for each of the plurality of time increments based on the first IAQ data set;

detecting a second IAQ data set within a second room at the plurality of time increments using a second IAQ detector in the second room;

determining a second IAQ health level for each of the plurality of time increments based on the second IAQ data set;

detecting an individual being located within the first room during a first time period of the plurality of time increments;

detecting the individual being located within the second room during a second time period of the plurality of time increments;

extracting the first IAQ health level for each of the plurality of time increments during the first time period from the first IAQ health level for each of the plurality of time increments that was determined;

extracting the second IAQ health level for each of the plurality of time increments during the second time period from the second IAQ health level for each of the plurality of time increments that was determined; and

combining the first IAQ health level for each of the plurality of time increments during the first time period and the second IAQ health level for each of the plurality of time increments during the second time period into a true IAQ health level graph.

15 . The non-transitory computer program product of claim 14 , wherein the operations further comprise: displaying the true IAQ health level graph on a computing device of the individual.

16 . The non-transitory computer program product of claim 15 , wherein the operations further comprise: transmitting the true IAQ health level graph to the computing device of the individual.

17 . The non-transitory computer program product of claim 14 , wherein detecting the individual being located within the first room during the first time period of the plurality of time increments further comprises:

detecting wireless communication of a computing device of the individual using the first IAQ detector.

18 . The non-transitory computer program product of claim 17 , wherein the wireless communication is a Bluetooth signal.

19 . The non-transitory computer program product of claim 14 , wherein the first IAQ detector is located in a fire detector.
