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. The printed circuit board (PCB) is designed in an Arduino shield form ...

· The SCD-30 is an NDIR sensor, which is a 'true' CO2 sensor, that will tell you the CO2 PPM (parts-per-million) 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 ...

· CO2 sensors. I used a "real" CO2 sensor that works by measuring the IR absorption of CO2 present in the air. The end of the video shows the glow of the small lamp in the sensor that is used to generate light with long wavelength components. The light is then measured by two sensors, one tuned to CO2 absorption and one for reference. These ...
This CO2 sensor module is designed to monitor 0-5,000ppm carbon dioxide levels using a dual beam light source and NDIR sensing technologies. By using the dual-infrared source principle, the CU-1107 sensor compensates for long-term drifts by design. Dual beam detection allows for superior stability and better accuracy over the predicted 10 year lifespan of the sensor. It can achieve equivalent ...
It uses non-dispersive infrared to detect the concentration of CO2 in the air. This makes it pretty immune to the percentage of oxygen in the air, and with no moving parts or chemical sensor elements it should have a fairly long lifespan. It can detect concentrations up to 5000 ppm, at which point most humans are unable to focus well, complain of “stuffy, stale air” and may also start to ...
Der ZMF-100-IR ist ein auf Infrarot-Absorptionsmessung basierender CO 2 -Sensor zur Erfassung der CO 2 -Konzentration mittels des optischen Messprinzips NDIR (nicht dispersive Infrarot-Absorptionsmessung). Mit seinem robusten, roten Aluminiumgehäuse eignet er sich perfekt für den industriellen Einsatz.

· IR sensor basically consist an IR LED and a Photodiode, this pair is generally called IR pair or Photo sensor work on the principal in which IR LED emits IR radiation and Photodiode sense that IR radiation. Photodiode resistance changes according to the amount of IR radiation falling on it, hence the voltage drop across it also changes and by using the voltage comparator (like LM358 ...
Stimulated by market demand that asks for gas sensors characterized by high repeatability, accuracy, competitive pricing and customer-focused technical support, Novasis Innovazione has designed and developed the Novagas infrared gas sensor, suited to measure the concentration of pollutant and toxic gases, including CO2, CO, CH4 (also biogas), HC, SO2, N2O, NO, etc.
Schule in Corona-Zeiten heißt auch stickige Luft in Klassenzimmern. Das bereitet Wissenschaftlern große Sorgen. Der Grund: viele Aerosole, hohe Ansteckungsgefahr. CO2-Messgeräte könnten helfen.
Nondispersive infrared (NDIR) spectroscopy is often used to detect gas and measure the concentration of carbon oxides (for example, carbon monoxide and carbon dioxide). An infrared beam passes through the sampling chamber, and each gas component in the sample absorbs some particular frequency of infrared.
Die Hauptkomponenten eines IR-CO2-Sensors sind Lichtquelle, Messkammer, Interferenzfilter und IR-Sensor. IR-Strahlung wird vonder Lichtquelle durch das gemes-sene Gas zum Sensor geleitet. Ein an der Vorderseite angebrachter Filter sorgt dafür, dass nur die Wellenlänge des gemessenen Gases den Sensor erreicht. Die Lichtintensität wird ermittelt und in einen Gaskonzentrationswert umgewandelt.

In the defined time intervals relays that control lights and CO2 are turned on or off. Additional sensors were added to read data about the aquarium and room. So far so good. The interesting part of the project is still to come: the time intervals, relay controls and sensors data are driven and stored by a PC running Linux and NodeJS server. The server stores sensor data in a database and ...
