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.
