1. A system for measuring gas or airborne compound concentration in a vehicle cabin comprising:
a 3D infrared time of flight camera having a field of view encapsulating at least a portion of a vehicle cabin and emitting light into the field of view,
a processor communicatively coupled to a computerized memory;
wherein the 3D infrared time of flight camera collects image data comprising a 3D view from the field of view, wherein the 3D view is created by light reflected back to the 3D infrared time of flight camera from a gas in the ambient air or an airborne particle in the ambient air;
wherein the computerized memory comprises software that uses the image data to calculate identification data regarding the gas and/or airborne particle in the ambient air, and wherein the processor is configured to transmit the identification data to a vehicle computer system;
wherein the vehicle computer system uses the identification data to trigger at least one remedial action for neutralizing the presence of the gas and/or airborne particle in the ambient air.
