  • System for checking filter of air cleaner for automobiles
    Patent number: 8574355
    Abstract: A system recognizes a check-up time of a filter of an air cleaner. The system includes a power unit that supplies power to the system, a pressure sensor that measure pressure of a filter, at an outlet connected with a filter unit, a conversion circuit that converts the measured value into a predetermined type, a processor that controls the measurement period of the pressure sensor and receives and compare the measured value converted by the conversion circuit with a predetermined reference value, and a display unit that displays a filter replacement period.
