Abstract
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.
Claims15
A composite sensor for sensing gas and dust by using a single heat source, the composite sensor comprising:
- 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 configured to transfer heat generated by the first light source to the dust sensor module.
A composite sensor for sensing gas and dust using a heat source, the composite sensor comprising:
- a base;
- a housing coupled to an upper surface of the base to form a space;
- a gas sensor coupled to the upper surface of the base in the space and comprising a solid electrolyte, a reference electrode, and a sensing electrode;
- and
- a dust sensor, a lens, and a light source coupled to the upper surface of the base in the space,
- the gas sensor emits heat during operation,
- the dust sensor senses dusts of a predetermined size or more among dusts moved by heat emitted from the gas sensor, and
- the housing comprises a first opening through which gas and dust are introduced on one sidewall and a second opening through which gas and dust are discharged on another sidewall.
