Abstract
The present disclosure relates to a color gas sensor module including an optical measurement device, a housing having an interior space therein and a gas movement passage allowing a gas to move from outside to the interior space, wherein the optical measurement device is provided in the housing and includes a light emitter that emit light and a light receiver that receives reflected light, and a gas sensor included in the housing and changing color by reacting with gas, wherein the light emitter emits light to the gas sensor, and the light receiver receives light reflected from the gas sensor.
Claims13
A color gas sensor module including an optical measurement device, the color gas sensor module comprising:
- a housing having an interior space therein and a gas movement passage allowing a gas to move from outside to the interior space;
- the optical measurement device provided in the housing and including a light emitter that emits light and a light receiver that receives reflected light;
- and
- a gas sensor provided in the housing and configured to change color by reacting with the gas,
- wherein the light emitter emits light to the gas sensor, and the light receiver receives light reflected from the gas sensor,
- wherein the gas sensor includes a nano-pattern layer on which patterns are formed,
- wherein the patterns are separated from each other, and
- wherein the nano-pattern layer is configured such that a distance between the patterns changes when reacting with the gas.
