We know that water, light and carbon dioxide are all necessary factors for plant growth. Among these three elements, water and sunlight are both visible to the naked eye, only carbon dioxide is invisible and intangible, and is often ignored by people. Carbon dioxide is one of the raw materials for plants to carry out photosynthesis, and the level of carbon dioxide concentration directly affects the growth quality of crops.

Carbon dioxide is the most ideal benchmark for measuring the air quality in the car. It is more sensitive than other air quality indicators. Whether it is different seasons or different times of the same day, the carbon dioxide content shows obvious changes. Therefore, it is very necessary to use carbon dioxide sensor to measure CO₂ concentration.

A carbon dioxide sensor is a machine used to detect the concentration of carbon dioxide. Carbon dioxide is one of the raw materials for photosynthesis of green plants, and 95% of the dry weight of crops comes from photosynthesis. Therefore, the use of carbon dioxide sensors to control the concentration has become an important factor affecting crop yield. Carbon dioxide is a colorless, odorless gas that is one of the most important components of the atmosphere. As the main reactant of photosynthesis, carbon dioxide concentration is directly related to the photosynthetic efficiency of crops, and determines the growth, maturity, stress resistance, quality and yield of crops.

A carbon dioxide sensor or CO2 sensor is an instrument for the measurement of carbon dioxide gas. The most common principles for CO2 sensors are infrared gas sensors (NDIR) and chemical gas sensors. Measuring carbon dioxide is important in monitoring indoor air quality, the function of the lungs in the form of a capnograph device, and many industrial processes.

Carbon dioxide sensor can effectively measure indoor carbon dioxide concentration, and NDIR CO2 sensor is often used for carbon dioxide monitoring in factories, workshops, greenhouses, clean rooms and other industries and agriculture, as well as ventilation control and environmental quality in homes, villas, office buildings, conference rooms, classrooms and other fields. The scope of application includes monitoring of CO2 concentration in the production of industrial, agricultural and residential environments and the use of carbon dioxide gas units.

A carbon dioxide sensor is a machine used to detect the concentration of carbon dioxide. Carbon dioxide is one of the raw materials for photosynthesis of green plants, and 95% of the dry weight of crops comes from photosynthesis. For those unfamiliar with air quality sensors, choosing the right sensor can be challenging. Today we are going to discuss the types of CO2 sensors and their pros and cons.

NDIR CO2 sensors monitor and detect for the presence of carbon dioxide based on the absorption of infrared light at a specific wavelength. An NDIR sensor comprises an infrared source, a light tube, a bandpass filter, and a detector. The target gas is determined through the filter wavelength choice.
