Abstract: A fine dust measurement module includes a fluid inlet through which a fluid including fine dust is introduced, a first channel through which first fine dust having at least a first diameter, among the fine dust introduced into the fluid inlet, passes, a second channel through which second fine dust having a second diameter that is less than the first diameter, among the fine dust introduced into the fluid inlet, passes, a fine dust detection sensor for sensing fine dust flowing into the second channel, a heater above the fine dust detection sensor, and an orifice upstream of a flow of the second fine dust from the fine dust detection sensor and the heater.
