Image sensor - Simple English Wikipedia, the free encyclopedia

An image sensor is an electronic device that can record an image.Usually, image sensors work by detecting the level, and intensity of light.Most sensors work on visible light and infrared light. There are special sensors which can detect X-Rays and Gamma Radiation.There are different ways in which to build such sensors: In 2020, the most common sensor technologies were CCD and CMOS

NDIR CO2 Sensor | SSU Ocean Instruments Wiki | Fandom

A non-dispersive infrared (NDIR) carbo dioxide (CO2) sensor is commonly used to measure atmospheric CO2 and partial pressure CO2 (pCO2) of seawater. The sensor is spectroscopic. CO2 molecules absorb infrared light. An infrared light is passed through a tube that the gas to be measured. The amount of infrared light absorbed is then measured. Therefore, the absorbance can be used to calculate ...

Ocean acidification - Wikipedia

Ocean acidification is the ongoing decrease in the pH of the Earth's oceans, caused by the uptake of carbon dioxide (CO 2) from the atmosphere. The main cause of ocean acidification is the burning of fossil fuels.Seawater is slightly basic (meaning pH > 7), and ocean acidification involves a shift towards pH-neutral conditions rather than a transition to acidic conditions (pH < 7).

Sensor fusion - Wikipedia

Sensor fusion is the process of combining sensory data or data derived from disparate sources such that the resulting information has less uncertainty than would be possible when these sources were used individually. For instance, one could potentially obtain a more accurate location estimate of an indoor object by combining multiple data sources such as video cameras, WiFi localization signals.

What to Know About CO2 Emissions | MOTOR

We multiply this by the number of grams of air measured by the MAF sensor (3.3 in this example) to calculate .4032 g of O2 destined to become part of the CO2. As before, we know from the periodic table that oxygen has an atomic weight of 16, while carbon has a weight of 12, so CO2 has a weight of 44.

Nondispersive infrared sensor - Wikipedia

A nondispersive infrared sensor (or NDIR sensor) is a simple spectroscopic sensor often used as a gas detector.It is non-dispersive in the fact that no dispersive element (e.g a prism or diffraction grating as is often present in other spectrometers) is used to separate out (like a monochromator) the broadband light into a narrow spectrum suitable for gas sensing.

Carbon monoxide detector - Wikipedia

Oct 18, 2005 · A carbon monoxide detector or CO detector is a device that detects the presence of the carbon monoxide (CO) gas to prevent carbon monoxide poisoning. In the late 1990s Underwriters Laboratories changed the definition of a single station CO detector with a sound device to carbon monoxide (CO) alarm.

Hydrogen sensor - Wikipedia

Hydrogen sensor. A hydrogen sensor is a gas detector that detects the presence of hydrogen. They contain micro-fabricated point-contact hydrogen sensors and are used to locate hydrogen leaks. They are considered low-cost, compact, durable, and easy to maintain as compared to conventional gas detecting instruments.
