NDIR Sensors - Global Industry Market Analysis Report 2020-2031

Non - Dispersive Infrared Sensors (NDIR Sensors) are gas - detection sensors that operate based on the principle of infrared absorption. They utilize the characteristic that different gases selectively absorb infrared light of specific wavelengths to detect the concentration of the target gas. The working principle is that when the continuous - spectrum infrared light emitted by the infrared light source passes through the gas chamber containing the target gas, the target gas molecules will absorb the infrared light energy of specific wavelengths, resulting in a decrease in the intensity of the infrared light transmitted through the gas chamber at the corresponding wavelengths. By detecting the change in infrared light intensity and according to the Lambert - Beer law, the concentration of the target gas can be accurately calculated.

This sensor mainly consists of an infrared light source, a gas chamber, a filter, an infrared detector, and other parts. The infrared light source is used to emit infrared light, providing a light - source basis for detection; the gas chamber is the space where the target gas exists, and the gas interacts with the infrared light here; the filter is used to screen out infrared light of a specific wavelength, enabling it to react with the target gas in a targeted absorption manner; the infrared detector is responsible for receiving the infrared light after passing through the gas chamber and the filter and converting the light signal into an electrical signal for output, facilitating subsequent processing and analysis.

In terms of market applications, NDIR sensors are extremely widely used. In the field of environmental monitoring, they are often used to detect harmful gases in the air, such as carbon dioxide, carbon monoxide, and methane. In industrial production, they can be used to monitor industrial exhaust emissions, ensuring that enterprise production complies with environmental protection standards; in indoor air quality monitoring, they can detect the indoor carbon dioxide concentration in real - time, helping to judge the indoor ventilation situation and ensuring people's health. In the field of vehicle exhaust detection, they can accurately measure the content of pollutants such as carbon monoxide and hydrocarbons in vehicle exhaust, contributing to the implementation of vehicle exhaust emission standards. In the medical field, they can be used to monitor the specific gas components in the exhaled gas of patients, assisting in disease diagnosis. For example, in the respiratory department, they are used to detect the nitric oxide content in exhaled gas to help diagnose lung diseases. In the agricultural field, they can monitor the carbon dioxide concentration in greenhouse sheds, optimize the plant growth environment, and improve crop yield and quality.

From the perspective of market development trends, with the increasing global attention to environmental quality, industrial safety production, and healthy living, the demand for NDIR sensors continues to grow. Technological innovation has become the key force driving market development. Researchers are constantly developing new infrared light sources to improve the stability and luminous efficiency of the light sources; improving filter technology to achieve more accurate wavelength selection; optimizing the performance of infrared detectors to enhance detection sensitivity and response speed. At the same time, to meet the needs of different application scenarios, sensors are developing in the direction of miniaturization, intelligence, and integration. Miniaturization is convenient for installation and use in equipment with limited space; intelligence can achieve functions such as automatic calibration, data processing, and remote transmission; integration integrates multiple gas - detection functions into one sensor, improving detection efficiency and the cost - performance of the equipment. However, market competition is also becoming increasingly fierce. Many sensor manufacturers have launched NDIR sensor products with their own characteristics, competing for market share by optimizing product performance, reducing costs, and improving after - sales service.
