21/11/2021· The SCD30 is an NDIR sensor, which is a ''true'' CO2 sensor, that will tell you the CO2 PPM (partspermillion) composition of ambient air. Unlike the SGP30, this sensor isn''t approximating it from VOC gas concentration it really is measuring the CO2 concentration! That means its a lot bigger and more expensive, but it is the real thing. Perfect for environmental sensing, scientific ...

The basic measurement principle is called nondispersive infrared (NDIR) gas detection, which is based on the absorption of infrared radiation at certain gas specific wavelengths in accordance with the BeerLambert law. The most common gases that are measured with this NDIR principle are carbon dioxide (CO2), methane (CH4) and hydrocarbons (HC).

The CDE are nondispersive infrared (NDIR) sensors designed for measuring environmental CO2 concentration in ventilation systems and indoor living spaces. Their measurement range of 0 to 2000 ppm makes them compliant with ASHRAE and other standards for ventilation control.

We demonstrate an ultracompact optical CO2 sensor by combining metamaterialenhanced MEMS components with an efficient multireflection cell (×× mm3). We measure a CO2 sensitivity of ppmCO2/√Hz at an energy consumption of mJ.

With all the talk of Co2 these days, you would think it’s easy to detect. But Co2 only consists of % of the atmosphere meaning; it’s a trace gas that’s quite difficult to detect. The Atlas Scientific EZOCO2 sensor is a compact NonDispersive Infrared (NDIR) sensor that gets right to the point, giving you the Co2 readings in ppm.

NDIR CO2 Sensors Alphasense CO 2 and Methane infrared sensors are supplied in the industry standard miniature (20mm diameter) gas sensor housing. Patented optics give the best signal to noise ratio of any 20mm diameter NDIR and universal linearisation constants allow easy implementation.

is used to detect the amount of a specific gas. For instance, since CO2 has a strong absorbance at a wavelength of µm, a bandpassfilter is used to remove all light outside of this wavelength. Figure below shows the basic NDIR gas sensor working principle. Figure 1. NDIR Gas Sensor Principle

Photodiode (Infrared sensor of NDIR CO2 sensor) Since the photodiode is a photo type detector, its response speed is overwhelmingly faster (typ. 2μs) than that of a thermal type detector. Therefore, by incorporating this photodiode into a NDIR gas sensor and combining with LED of an infrared light emitter, the power consumption can be reduced to the minimum.
