[ Focus on Chemical Machinery and Equipment Network ] Since the 2021 government work report listed “solidly doing carbon peak and carbon neutral tasks” as one of the key tasks, how to achieve the goal of “carbon neutrality” has also become a sensor Hot topic in the circle
.
The first step of carbon neutralization is to confirm carbon emissions, and carbon dioxide sensors are indispensable

Chemical machinery equipment network hotspots focus on chemical machinery equipment sensors.
The first step of carbon neutralization is to confirm carbon emissions, and carbon dioxide sensors are indispensable
.
On the road to carbon reduction, companies have a long way to go
The definition of carbon neutrality: Carbon neutrality refers to the calculation of the total amount of greenhouse gas emissions produced directly or indirectly by enterprises, groups or individuals within a certain period of time, and then offset their own carbon dioxide generation through plant afforestation, energy saving and emission reduction, etc.
Emissions, to achieve "zero emission" of carbon dioxide

Let's first look at the current status of global carbon emissions.
Looking at the world, power generation consumption is the largest source of carbon dioxide
.
The secondary sources of carbon dioxide in developed economies (the United States and the European Union) are transportation and construction consumption, while the secondary sources of developing economies (China, India) are mainly concentrated in industrial combustion

★ Step 1: Calculate the carbon footprint and establish a low-carbon system
.
Carbon footprint calculation is to conduct emission source inventory and data collection for all the sources of greenhouse gas that may be generated by the company, so as to understand the source of the company's greenhouse gas emission and quantify the collected data information

Through the inventory of corporate emission sources, we can learn more about the company’s carbon emission sources and amounts, and formulate a series of effective measures accordingly to reduce the carbon emissions generated by the company’s production operations and other activities

Application and development trend of carbon dioxide sensor market
Carbon dioxide content is an important indicator of air quality.
When the carbon dioxide concentration exceeds a certain standard, people will feel uncomfortable
.
WHO recommends keeping indoor carbon dioxide concentrations below 1000 ppm as much as possible
.
When the carbon dioxide concentration exceeds a certain standard, people will feel uncomfortable
.
WHO recommends keeping indoor carbon dioxide concentrations below 1000 ppm as much as possible
.
The concentration of carbon dioxide and the physiological reaction of the human body are as follows:
350～450ppm: same as general outdoor environment
350～1000ppm: fresh air, smooth breathing
1000～2000ppm: Feel the air muddy and start to feel drowsy
2000～5000ppm: Feeling headache, drowsiness, sluggishness, inability to concentrate, rapid heartbeat, mild nausea
Greater than 5000ppm: may cause severe hypoxia, causing permanent brain damage, coma, and even death
At present, in the field of indoor air quality monitoring, carbon dioxide sensors have been widely used
.
The carbon dioxide monitoring system can be linked to the fresh air system.
Once the carbon dioxide concentration exceeds the standard, it can be linked to related equipment for exhaust and ventilation

In addition, carbon dioxide sensors are also very useful in the medical field.
For example, the high-speed response carbon dioxide sensor is indispensable for the ventilator used in the treatment of the new coronavirus to monitor the carbon dioxide content
.
The burning of fossil fuels produces a large amount of carbon dioxide, and long-term monitoring of carbon dioxide emissions is required in this area

The technology of growing vegetables in greenhouses has brought great convenience to mankind.
Among them, the carbon dioxide concentration of vegetables is generally 1000ppm to 1500ppm, so carbon dioxide sensors are usually installed in plastic greenhouses to ensure that the carbon dioxide concentration is insufficient in time to alarm

The problems of individual sensor devices may not be solved in a short time.
Algorithms can be used to compensate and improve.
Multiple gas sensors of the same or different types are formed into a sensor array, and their signals are processed.
Advanced algorithms are used to obtain more useful information.
Value information to improve the performance of measuring instruments
.
In order to adapt to the upgrade trend of the consumer market, the gas sensor industry will gradually develop in the direction of low cost, functionalization, integration, miniaturization, and intelligence, and the speed of upgrading will be accelerated
