Well the science behind using carbon dioxide is kinda simple! Why are they made? To catch people like asylum-seekers and refuges who are doing bad. They detectors sense carbon dioxide. Carbon dioxide is science so you have to explain about carbon dioxide and respiration. We give out co2 afta breathin in oxygen right? well that's science! there you go quite simpal init..?!
Carbon dioxide detectors are used to identify and to measure carbon dioxide concentration in the atmosphere. These detectors are near infrared detectors or chemical detectors.
Because it skins of poo
It wastes energy
sonars can be used as detectors on roads...
Co2 is not combustible - it is the end product of combustion reactions or the decaying organic matter and will not be broken down any further by that mechanism. Most of the world's CO2 is produced by rotting trees and matter decaying in our Oceans (96%). co2 in used in combustion of biomass i.e co2 biomass gasification. this is only possible at higher temperatures. co2 can used in chemical synthesis co2 is used produce ch4 ( carnol process) co2 supports combustion of metals. search in sciencedirect.com
I'm assuming you're talking about the absorption of CO2 into water. CO2 free water is used to properly measure the amount of CO2 water can actually absorb. CO2 already in the water will reduce the mass of CO2 transferred from the gas, and while I don't believe that there is a specific point at which CO2 can no longer be absorbed by water, the tendency for CO2 to be absorbed into water with CO2 already in it is reduced.
smoke detectors
O=C=O carbon dioxide
CO2 detectors are used for detecting levels of carbon monoxide in the air. Many people use CO2 detectors in their homes to prevent carbon monoxide poisoning.
i dn't
the co2 Detectors detects co2 and in the thing they should be about 0.03 co2 if not they something living in there
CO2 (carbon dioxide) is present in the breath exhaled by the body. Sensitive CO2 detectors sample the air from inside trucks as they arrive from Europe. They can detect illegal immigrants hiding in the truck as the level of CO2 would be higher than it would be if people hadn't been in there breathing out CO2 for ages while the truck crossed The Channel.also they of couldn't of breathed with air for the the journey
they were used in border control because they were trying to stop illegal immigrints going from country to country;so the detectors monitor the level of co2 in the lorry and if it is over a certain number they searched the lorry wolfiepagefan001
Rechargable batteries are a good option for CO@ detectors,please make sure you cahrge them regularly.
The first smoke detectors are based on optical principles - photoelectric detectors.
Americium become to be largely used in smoke detectors after 1970.

Americium (isotope 241) is the most common radioactive element used in smoke detectors.
They use them by puting CO2 (carbon dioxide) detectors around a truck to pick up tiny movements or to sense breathing inside the truck. But only if they think that someone is in the truck they will send it to a detector shed where the detector shed will do the same thing as the Carbon dioxide Dectectors
