ACD1200 High-performance Sensor Utilizes Non-Dispersive Infrared (NDIR) Principle To Detect Concentration Of Carbon Dioxide In The Air

The ACD1200 is a high-performance sensor that utilizes the Non-Dispersive Infrared (NDIR) principle to detect the concentration of carbon dioxide in the air. Here is a detailed introduction:

Principle

The ACD1200 is based on the NDIR principle. Its main components include an infrared (IR) source, a sample chamber, a light filter, and an infrared detector. The IR light emitted by the source passes through the sample chamber, and the carbon dioxide gas in the sample chamber will absorb specific wavelengths of infrared light according to the Beer-Lambert law. The infrared detector measures the attenuation of these wavelengths, and then calculates the concentration of carbon dioxide in the air through a specific algorithm.

Features:

• Good Selectivity: It can specifically detect carbon dioxide and has little response to other gases, which can effectively avoid interference from other gases and ensure the accuracy of detection results.
• No Oxygen Dependence: Unlike some other gas sensors that may be affected by the oxygen content in the air, the detection performance of the ACD1200 is not affected by oxygen concentration, so it can be used in various oxygen environments.
• Long Service Life: The sensor has a reasonable structural design and selects high-quality materials, which enables it to maintain stable performance during long-term use and has a relatively long service life.
• Convenient Digital Interface Output: It is equipped with a digital interface, which can conveniently communicate with other devices, such as transmitters, controllers, or data acquisition systems, facilitating the integration and data processing of the entire system.

Application:

The ACD1200 is often used in fields such as indoor air quality monitoring, ventilation systems, and environmental protection monitoring. In indoor environments, it can monitor the carbon dioxide concentration in offices, classrooms, hospitals, and other places to provide a basis for adjusting ventilation volume and ensuring good air quality. In ventilation systems, it can be used as a key component to realize the automatic control of the system and maintain the stability of carbon dioxide concentration.
