Application of mixed gas sensor in air conditioner

Abstract

The invention relates to application of hybrid gas sensor to an air conditioner. The hybrid gas sensor combined with a peripheral circuit module is placed nearby an air intake of the air conditioner; the hybrid gas sensor detects quality of air and outputs corresponding resistance to the peripheral circuit; a variable resistor reflecting air quality in the peripheral circuit is connected with an A / D sampling circuit; the A / D sampling circuit transmits collected analog voltage signals to a control chip through an A / D sampling port; after the control chip converts the analog voltage signals into digital signals, the control chip judges grade of the air quality and outputs the grade to a display screen of the air conditioner; and when the air quality declines to a certain grade, a buzzer is started to send out a sound to alarm. The hybrid gas sensor is used for replacing heavy specialized detection equipment to detect the air quality, so that analysis of the air quality can be widely applied to daily life; and display and alarming functions of the hybrid gas sensor are combined to greatly reduce probability of harmful gas injury, thereby improving life quality of people.

Description

technical field [0001] The invention relates to the application of sensors, in particular to the application of mixed gas sensors in air conditioners. Background technique [0002] With the improvement of people's living standards, people pay more and more attention to the quality of life, but with the rapid development of industry, the emission of harmful gases, automobile exhaust and other exhaust gases, as well as the pollution caused by decoration, have seriously polluted the air. , brings more and more inconvenience to people's daily life, people also begin to pay attention to the air quality problem of their living space, especially the problem of indoor air quality, more and more people choose to carry out indoor air environment testing, and It takes a lot of time and a lot of money to buy various harmful gas removers, and the gain outweighs the gain. [0003] Nowadays, professional formaldehyde removal machines are generally used in daily life. There may be a large ...

[0002] With the improvement of people's living standards, people pay more and more attention to the quality of life, but with the rapid development of industry, the emission of harmful gases, automobile exhaust and other exhaust gases, as well as the pollution caused by decoration, have seriously polluted the air. , brings more and more inconvenience to people's daily life, people also begin to pay attention to the air quality problem of their living space, especially the problem of indoor air quality, more and more people choose to carry out indoor air environment testing, and It takes a lot of time and a lot of money to buy all kinds of harmful gas removers, which is not worth the candle

[0003] Nowadays, professional formaldehyde removal machines are generally used in daily life. There may be a large amount of formaldehyde in the newly renovated house, which needs to be removed. At that time, it will gradually lose the need to use it as time goes by, causing invisible waste; and This kind of gas detection and removal is for a single gas, and it cannot detect and remove most harmful gases, such as gas, carbon monoxide, ethanol and other gases that are harmful to the human body. This machine cannot even detect them, so in most cases , what people need to know most is whether the gas in their own space is harmful to the human body, not just limited to a certain kind of gas that is harmful to the body

[0004] Air conditioners are also called space air conditioners. As the name implies, they are a kind of machine that adjusts the air in the space. However, the function of the air conditioners on the market is only limited to adjusting the temperature in the space, and cannot detect the quality of the air in the space.
