1. A system for determining an event in a cabin of a vehicle, the system comprising:
a gas sensor configured to generate a first sensor signal associated with a quantity of at least one gas or volatile organic compound (VOCs) in ambient air of the cabin;
a particulate matter (PM) sensor configured to generate a second sensor signal associated with a quantity of particulate matter in the ambient air of the cabin;
an image sensor configured to generate an image signal corresponding to a captured image of at least a portion of the cabin of the vehicle; and
a controller operably connected to the gas sensor, the PM sensor, and the image sensor and configured to:
receive the first and second sensor signals from the gas sensor and the PM sensor;
generate a first time series dataset of the first sensor signals and a corresponding second time series dataset of the second sensor signals;
determine an event in the cabin of the vehicle by analyzing both the first and second time series datasets using a machine learning model that has been trained with training data corresponding to time series data of PM readings and gas sensor readings of known events; and
in response to determining the event in the cabin, operate the image sensor to generate image data corresponding to a captured image of at least a portion of the cabin of the vehicle.
