Within these monitors a small CO2 sensor cells exists that actually senses the CO2 molecules in the air. The CO2 detectors range from $50 up to $1000. Most CO2 monitors employ CO2 sensors that employ non-dispersive infra-red (NDIR) sensing technology. An example of carbon dioxide monitors and how they look like is here.
NDIR CO2 Sensor - Air Quality Indicator for Indoor Public Areas. Under the global epidemic spread of COVID-19, many countries have taken actions to improve ventilation to chase away COVID-19. The targets are to improve the air circulation in public buildings, public offices, museums, theatres, universities and schools, so as to help stop the ...
Dec 10, 2020· high concentrations (due to some indoor emission sources or an intake from outdoor air) are another key indicator for air quality. eLichens has designed the eLsi station that integrates, in addition to the NDIR CO2 sensor, particle sensors, TVOCs and environmental parameters (temperature, humidity, sound and light intensity). The goal is to ...
All carbon dioxide sensors need calibration. Depending on the application, this can be accomplished by calibrating the sensor to a known gas or using the automatic baseline calibration (ABC) method. Both have pros and cons you should know. Most of our CO2 products use non-dispersive infrared (NDIR) carbon dioxide sensors.

That is why the recommendation to do outdoor activities has become popular: as the concentration of aerosolized virus is very small, the risks of getting infected is as well. ... “The most important thing is that the meter that we are going to buy has a built-in NDIR sensor since this will give us greater ...
Although it looks like a retro Nokia, this air quality tester really comes in handy for measuring CO2 levels, temperature, and humidity. The NDIR sensor claims to provide very accurate readings, so that the device is also compatible with reading the environmental conditions in an office, as well as a lab.
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 it's a lot bigger and more expensive, but it is the real thing.
Non-dispersive infrared sensing element (NDIR) Field replaceable CO2 sensor. 15+ year life expectancy on CO2 sensing element. Industry leading 7-year limited warranty on electronics; NDIR module 3 years. Internal heater for reliable outdoor operation. Selectable auto-calibration mode returns sensor to baseline values. ±40ppm, ±3% of reading.
SCD30 - Sensor Module for HVAC and Indoor Air Quality Applications. CMOSens® Technology for IR detection enables highly accurate carbon dioxide measurement at a competitive price. Along with the NDIR measurement technology for CO 2 detection, a best-in-class Sensirion humidity and temperature sensor is also integrated on the same sensor module.
NDIR is an industry term for "nondispersive infrared", and is the most common type of sensor used to measure carbon dioxide, or infrared (IR) lamp directs waves of light through a tube filled with a sample of air toward an optical filter in front of an IR light detector.
The AQO provides valuable information on outside air conditions in both BACnet and analog formats. CO2, relative humidity and temperature measurement all from one outdoor rated enclosure. The standard LCD, gasketed lid and field replaceable CO2 element make initial installation and future service a breeze. The AQO can also be customized with optional RTDs or thermistors .
