Claim 0:
1. A particle matter analysis device comprising:
a charger configured to receive power from a power supply device and to charge particles included in intaken air;
an electrophoretic mobility particle collector configured to collect particles having electrophoretic mobility greater than a predetermined electrophoretic mobility among the charged particles based on an electrophoretic mobility and to measure a current of electrophoretic mobility particles;
an aerodynamic particle collector configured to collect charged particles passing through the electrophoretic mobility particle collector based on an inertial force of the charged particles and to measure a current of aerodynamic particles;
a filter configured to collect charged particles passing through the aerodynamic particle collector and to measure a current of filtered particles; and
a processor,
wherein the processor calculates a density of the particles based on a ratio of the current of electrophoretic mobility particles, the current of aerodynamic particles, and the current of filtered particles.
