The circuit shown in Figure 1 is a complete thermopile-based gas sensor using the NDIR principle. This circuit is optimized for CO2 sensing, but can also accurately measure the concentration of a large number of gases by using thermopiles with different optical filters.
Yukon CO2 also contains a Relay that is activated when the value of Carbon Dioxide in ppm has overcome the maximum threshold set (by default or by the user). To largely involve the user and adapt the device in accordance to the needs, the alarm threshold (900 ppm by default) can be set from a minimum of 700 ppm, to a maximum of 1500 ppm. In case of a “dangerous” situation, the device ...
These NDIR CO2 sensors measure temperature, relative humidity and CO2. Carbon dioxide or CO2 is a result of human metabolism. Moderate to high levels of CO2 can cause headaches and fatigue. To prevent or reduce high concentrations of carbon dioxide in a building or room, fresh air should be supplied to the room.
Die E+E CO2-Sensoren basieren auf dem NDIR-Zweistrahlver-fahren (2 Wellenlängen / 2 Detektoren). Ein Detektor ist auf die Wellenlänge von 4,2 μm eingestellt, die von CO2 absorbiert wird. Der zweite Detektor ist auf eine Wellenlänge von 3,9 μm …

Researchers have found that NDIR sensing technology is able to monitor diurnal CO 2 patterns (Hari et al. 2008; Johnson et al. 2010) with accuracy comparable to that of conventional methods, and with the added bonus of being manageably sized, making deployment easier (Fiedler et al. 2013). Even in situations where the sensors experienced large changes in temperature and pressure over short (1 ...

Abstract:In this paper, we propose a novel, miniaturized non-dispersive infrared (NDIR) CO2sensor implemented on a silicon chip. The sensor has a simple structure, consisting of a hollow metallic cylindrical cavity along with access waveguides. A detailed analysis of the proposed sensor is presented.
Bacharach’s MGS-250 Infrared Gas Detector is a cost-effective solution for compliance with refrigeration safety codes (ASHRAE 15, CSA-B52) and emissions reduction standards (F-Gas, CARB).. Long-life, proprietary infrared (NDIR) sensor provides 5-7 years of maintenance-free service while detecting the presence of a target gas down to 20 ppm Minimum Detection Level (MDL)
Non-Dispersive Infrared (NDIR) technology is the most common method of measuring CO˚ in Indoor Air Quality analyses. The NDIR sensor consists of the following (see image below): 1) Infrared (IR) Lamp, 2) Gas Sample Chamber, 3) Wavelength Filter, and 4) an IR Detector.
