As we all know, carbon dioxide is an important part of the earth's atmosphere, and carbon dioxide is also a common gas in our daily life. It is not only the main reactant of photosynthesis of green plants, but also a major "killer" of environmental pollution ". When we breathe in oxygen, we exhale carbon dioxide. Although carbon dioxide is colorless and tasteless, invisible and intangible, it isOur lives are closely related. With the development of science and technology and the improvement of people's awareness of environmental protection, quantitative monitoring and control of carbon dioxide gas has become a new and growing demand in the fields of household, shopping malls, agriculture, medical, automobile and environmental protection.

Speaking of carbon dioxide, I believe everyone is familiar. The content of carbon dioxide in the air is generally0.04%, People within this range will not be harmed. If there are many people gathered indoors, the air will not circulate.CO2Sensors can be used in air conditioning systems or air quality monitors to control air quality in a targeted manner. This method helps to improve the health of the human body and improve work efficiency. Scientific research has found that as long as the indoor carbon dioxide concentration reaches1000 ppm(one in a million), it will make people drowsy and affect concentration. If the carbon dioxide is too high, it will also stimulate the respiratory center, resulting in shortness of breath, increased smoke inhalation, headache, unconsciousness and other symptoms.

In order to solve these situations, cultural museums, residences, hospitals and schools are usually equipped with belts.CO2monitoredFresh air system, the fresh air system can filter and purify the outdoor air into the room, and at the same time discharge the indoor turbid gas to keep the indoor air fresh and clean. The carbon dioxide sensor can also accurately monitor the indoor carbon dioxide concentration value, and on this basis, accurately control the ventilation time of cultural museums, residences, hospitals, schools and other places, thereby saving energy. At the same time, it can also use the ventilation system on demand based on accurate sensor data, reducing the operating cost of the ventilation system.

Apart from that,CO2Agricultural production is also closely related. With the development of science and technology, planting techniques such as agricultural greenhouses, plant factories, and mushroom cultivation houses have also emerged. This kind of technology is mainly used to provide plants with suitable environmental conditions for their growth, so as to achieve the purpose of cultivation under the originally unsuitable season and geographical conditions. There are many factors in planting that need to be controlled, such as temperature, humidity,CO2concentration, light intensity, etc. Only by controlling these factors related to plant growth in a suitable range, can we ensure the normal growth of plants and obtain better results.

Through the Internet of Things connected to the sensor inside the greenhouse air temperature and humidity, carbon dioxide solubility, light intensity, soil temperature and humidity, soil.ECValue, soil pH, soil nutrient content, etc. are collected in real time and uploaded to the cellular smart cloud platform. Users can use the mobile terminal applet orPCThe end big data platform can be viewed in real time and alarm in case of abnormality.

CO2Gas monitoring is so important to our daily lives, thenCO2SensorMainly depends on the humidity conditions in the application environment, if the environmental humidity is small, but also consider the cost, such as smart home, fresh air system and other environments, you can choose a single-channel sensor; if the humidity is large, like agricultural greenhouses, smart farming, etc., it is best to choose a dual-channel sensor that resists high humidity.
