16/10/2020· A study on NDIR-based CO2 sensor to apply remote air quality monitoring system. ICCAS-SICE 2009-ICROS-SICE International Joint Conference 2009, Proceedings (IEEE, 2009). 14.
Carbon dioxide (CO₂) is a colorless gas with a density about 60% higher than that of dry air. Carbon dioxide is odorless at normally encountered concentrations, however, at high concentrations, it has a sharp and acidic odor. It is a versatile industrial material, used, for example, as an inert gas in welding and fire extinguishers, as a pressurizing gas in air guns and oil recovery, as a chemical feedstock and …
01/11/2015· In this paper, a three-gas detection system with a environmental parameter compensation method is proposed based on Non-dispersive infra-red (NDIR) technique, which can be applied to detect multi-gas (methane, carbon dioxide and carbon monoxide). In this system, an IR source and four single-channel pyroelectric sensors are integrated in the miniature optical gas …
This portable CO2 meter uses NDIR (non-dispersive infrared) technology to ensure reliability and long term stability. It's useful in verifying HVAC system performance and air ventilation control. Poor indoor air quality is considered unhealthy because it causes tiredness, loss of ability to concentrate, and even illness (ex. Sick Building Syndrome). IAQ monitoring and survey, especially on CO2 level and air …
EZO-CO2™ Embedded NDIR Carbon Dioxide Sensor - Atlas Scientific The Atlas Scientific EZO-CO2™ Embedded CO2 Sensor uses a non-dispersive infra-red (NDIR) gas detection cell to derive CO2 content in a gaseous matrix. The NDIR detection cell is a single wavelength spectrophotometer that has been specifically designed to detect μm infrared radiation. The EZO-CO2™ comes with:One …
Principle of NDIR CO2 sensors The NDIR(Non-Dispersive Infrared) utilizes the phenomenon that a gas The amount of absorbed IR light is proportional to the concentration. For example, H2O has the maximum absorbance at and ㎛, SO2 at ㎛, CO2 at ㎛, NO at ㎛. An IR source at the end of the measurement chamber emits light into light at its characteristic wavelength. The filter …

TSI’s IAQ instruments measure carbon dioxide concentration by relying on one of the natural properties of CO 2 molecules: CO 2 molecules absorb light at a specific wavelength of µm. This wavelength is in the infrared (IR) range. High concentrations of CO 2 molecules absorb more light than low concentrations. This technique is called non-dispersive infrared (NDIR) detection. Refer to the …
