A composite sensor for sensing gas and dust by using a single heat source, according to an embodiment of the present invention, can comprise: a base; a gas sensor module comprising a gas sensor and a first light source in a first space; a dust sensor module comprising a dust sensor, a lens, and a second light source in a second space; and a heat transfer wall for transferring heat generated by the first light source to the dust sensor module.

Composite sensor for sensing gas and dust by using single heat source

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.
