1. A system for filtering exhaust gases of a vehicle, the system comprising:
an exhaust filter assembly comprising:
an enclosure having an inlet coupled with an end of an exhaust pipe of the vehicle to allow exhaust gases of an internal combustion engine of the vehicle into the enclosure;
at least one filter element fitted with the enclosure to adsorb gaseous particles and adsorb any or a combination of moisture particles, odours and unburned fuel mist particles of the exhaust gases, and allow remaining exhaust gases to flow out of the enclosure;
a set of sensors operatively coupled to the filter element to sense gaseous particles adsorbed on the filter element, and generate first signals in real-time based on the sensed gaseous particles, wherein the set of sensors comprises carbon monoxide (CO) sensors, carbondioxide (CO2) sensors, nitrogen particle sensors, and sulphur oxide (SOx) sensors, wherein at least one filter element is an activated carbon filter;
a control unit operatively coupled to the set of sensors, the control unit comprises one or more processors and a memory coupled to the one or more processors, the memory storing instructions executable by the one or more processors to:
receive the generated first signals;
generate in real-time second signals based on the received first signals, the second signals corresponding to an amount of the sensed gaseous particles adsorbed on the filter element; and
a communication unit, having the one or more processors, to transmit the second signals to one or more computing devices of one or more users to notify the one or more users.
