Abstract

A traffic pollution indicator mounts to an air vent of a car or other vehicle to detect pollution and present pollution information to passengers. The traffic pollution indicator includes one or more sensors for detecting pollution, one or more microcontrollers and one or more communication devices to communicate with one or more display devices. Pollution is typically detected as a change in pollution levels by the traffic pollution indicator. Various display devices or a screen of the traffic pollution indicator present sensor information, in various visual representations, to passengers.

Claims

1. A traffic pollution indicator for a vehicle comprising:

one or more uncalibrated sensors that output a signal varying with time, representing variations in an aggregate concentration of gases with time of one or more types of pollution, without carrying at any time any information on any absolute gas concentration;

a microcontroller that receives the signal and generates a digital representation of the signal;

a wireless communication device that transmits the digital representation to a display device;

an enclosure housing at least the microcontroller; and

a mount attached to the enclosure and comprising one or more air vent engagement elements for attaching the enclosure to an air vent of the vehicle;

wherein the display device comprises a screen and receives the digital representation from the wireless communication device and presents a visual representation of the digital representation on the screen;

wherein the signal is only generated when at least one of the variations in the aggregate concentration exceeds a predefined or calculated threshold.

2. The traffic pollution indicator of claim 1, wherein the display device is a computing device selected from the group consisting of smartphones, computers, tablets, and vehicle entertainment systems.

3. The traffic pollution indicator of claim 1 further comprising a power cable extending from the enclosure.

4. The traffic pollution indicator of claim 1 further comprising one or more additional sensors that detect additional sensor information selected from the group consisting of temperature, humidity and particulate concentration information.

5. The traffic pollution indicator of claim 1 further comprising a storage device housed in the enclosure, wherein the storage device stores the digital representation.

6. The traffic pollution indicator of claim 1, wherein the display device outputs an alert when at least one of the variations in the aggregate concentration exceeds a predefined or calculated threshold.

7. The traffic pollution indicator of claim 1, wherein the one or more air vent engagement elements are jaws biased toward a closed position with a biasing device.

8. The traffic pollution indicator of claim 1 further comprising an additional screen that presents the visual representation of the digital representation, wherein the additional screen is housed in the enclosure.

9. The traffic pollution indicator of claim 1, further comprising an audio output device that emits an alert when at least one of the variations in the aggregate concentration exceeds a predefined or calculated threshold.

10. The traffic pollution indicator of claim 1, wherein the visual representation includes one or more pollution graphs.

11. The traffic pollution indicator of claim 1 further comprising a power source housed within the enclosure.

12. The traffic pollution indicator of claim 1, wherein the display device executes machine readable code fixed on a non-transient storage medium to generate the visual representation.

13. The traffic pollution indicator of claim 1, wherein the screen identifies individual highly polluting vehicles in traffic by displaying an alert indicating the same when at least one of the variations in the aggregate concentration are of a particular amplitude.

14. The traffic pollution indicator of claim 13, wherein the screen also presents instructions to follow a vehicle along with the alert.

15. A method for displaying pollution information in a vehicle comprising:

securing a traffic pollution indicator to an air vent of the vehicle with a mount, the traffic pollution indicator comprising one or more uncalibrated sensors that output sensor information comprising a signal varying with time, representing variations in an aggregate concentration of gases with time of one or more types of pollution, without carrying at any time any information on any absolute gas concentration, and one or more microcontrollers that receive the sensor information and generate a digital representation of the sensor information;

receiving the digital representation at a display device; and

presenting a visual representation of the digital representation on a screen of the display device;

wherein the sensor information is only generated when at least one of the variations in the aggregate concentration exceeds a predefined or calculated threshold.

16. The method of claim 15 further comprising generating the visual representation by converting the digital representation into one or more pollution graphs.

17. The method of claim 15, wherein the digital representation is received via wireless communication.

18. The method of claim 15, wherein the traffic pollution indicator is secured such that the one or more sensors are oriented to face the air vent.

19. The method of claim 15 further comprising outputting an alert when at least one of the variations in the aggregate concentration exceed a predefined or calculated threshold.
