Abstract
Provided is a dust measurement apparatus for accurately measuring the dust concentration of two spaces and minimizing the possibility of noise generation, comprising: a dust sensor; a body housing having the dust sensor loaded therein, and having an inner space; a first outer hole and a second outer hole, which are respectively formed at two points of the body housing so as to connect the outside and the inner space; a first fan and a second fan, which are provided at the positions corresponding to each of the first outer hole and the second outer hole and driven so as to form a flow toward the inner space from the outside; and a control part for selectively driving the first fan or the second fan.
