Abstract

The invention discloses a gas sensor inside a building. The gas sensor comprises a casing, a light source, electric heating wires and a grid, wherein the light source is arranged at the top of the casing; the electric heating wires are arranged on the inner side of the casing; the grid is mounted in the middle of the casing; a gas inlet pipe and an exhaust pipe are arranged on one side of the casing; a temperature adjuster is arranged on the other side of the casing and electrically connected with the electric heating wires; a light filter is arranged at the bottom of the casing; a photoresistor is arranged at the lower end of the light filter; a direct-current power supply and a current amplifier are arranged on two sides of the photoresistor respectively; the direct-current power supply, the photoresistor and the current amplifier are electrically connected in sequence. The gas sensor inside the building facilitates detection for gas concentration, and the light filter is good in corrosion resistance, high in hardness and long in service life.

Description

technical field [0001] The invention relates to a gas sensor inside a building. Background technique [0002] Building is a kind of space for people to live and use that people use soil, bricks, tiles, stone, wood; (reinforced concrete, profiles in modern times) and other building materials, such as houses, bridges, factories, gymnasiums, caves, water towers, Temples and more. Broadly speaking, landscape and gardens are also part of architecture. In a more general sense, the consciously constructed nests of animals can also be counted as buildings. Xizhe has a saying: architecture is solidified music, and architecture is a history book of stone. The classic masterpiece "Ten Books of Architecture" by the ancient Roman architect Vitruvius put forward three standards of architecture: firmness, practicality, and beauty, which have always influenced the development of architecture in later generations. There are three elements of architectural composition: architectural funct...
