Tindie Blog | CO2 sensor

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 ...

New Products 8/11/21 feat. Adafruit SCD-41 – NDIR CO2 ...

· The SCD-41 is a photoacoustic ‘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 it’s bigger and more expensive, but it is the real thing. Perfect for environmental sensing, scientific experiments, air ...

DIY IR Sensor Module Circuit Diagram

· 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 ...

Aquarium Control & Monitoring - Arduino Project Hub

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 ...

Low Cost IR CO2 Sensors -

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 ...

Messen von Kohlendioxid - Vaisala

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.

mute&vent - mute button with CO2 warning |

· 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 ...
