Gravity: CCS811 Air Quality Sensor can measure the eCO2 (equivalent CO2) and TVOC (Total Volatile Organic Compounds) density. It can be widely used in many applications, such as air quality detection, air purifiers, ventilation system and so on. This CCS811 air quality sensor uses AMS's unique micro-hot plate technology.
Introduction. Digital Weight Sensor Module is based on HX711 module, which is a precision 24-bit analog-to-digital convertor designed for a weight scale. It also designed for industrial control applications to interface directly with a bridge sensor. Compared with other chips, HX711 not only has a few basic function, but also contains high integration, fast response, immunity, and other features.
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
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 ...
Introduction. DFRobot released its latest wide range infrared CO2 sensor, whose effective range is up to 0~50000ppm. This sensor is based on non-dispersive infrared (NDIR) technology and has good selectivity and oxygen-free dependency. It integrates temperature compensation and support UART communication mode.
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 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.

En sensor är ett samlingsbegrepp på en apparat eller anläggning som insamlar, konverterar och i vissa fall distribuerar någon form av signal, stimuli eller data. Våra fem sinnen kan betraktas som olika biologiska sensorer. Historia. På 1950-talet blev industrierna större och tillverkning började alltmer automatiseras, och en nya typ av ...
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.
Sensors for carbon dioxide are an example of this approach and they have been commercially available for several years. Cross sensitivity of electronic chemical sensors may also be utilized to design chemical sensor arrays , which utilize a variety of specific sensors that are cross-reactive for fingerprint detection of target gases in complex mixtures.
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.
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. 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.
