Because carbon monoxide can be found in any color and is odorless but cannot be tasted or smelled, it must be detected with a detector that was designed specifically for the purpose. Although there are smoke alarms that also act as carbon monoxide monitors, this isn't possible with a standard smoke alarm. Because carbon monoxide gas can damage the body or even kill, it's important to be protected by an early detection detector. You can get the best CO2 meter in this sites.
Any fuel can be incompletely burned to produce carbon dioxide, such as wood, gas, diesel, and petrol. The molecules reach the body's lungs and attach to the hemoglobin of the red blood-cells. This is 240x as appealing than the oxygen the cells would normally carry. As a result, oxygen is depleted in every part of the body including the head. Carbon monoxide concentrations can have a wide range of effects, from a mild headache to death. If a carbon monoxide victim is removed from the affected area after recovery, they may experience various after-effects. Carbon monoxide poisoning inflicts severe effects on a large number of people.
The importance of having a reliable system to detect carbon monoxide buildup is paramount. Many different technologies are used to make carbon monoxide sensors, and each one has certain advantages.
Electrochemical
In the UK, and in Europe as a whole, fuel cells are used for this carbon monoxide detection type. It has an electrode and electrolyte that is typically sulfuric. The carbon monoxide will be oxidized on one electrode, while the oxygen consumed by the other. This allows it to measure even the lowest levels of carbon dioxide, which are well below danger concentrations. However, when the amount of carbon monoxide is high enough to warrant a warning, an electrical circuit completes and an alarm is activated. It is a very precise sensor, with most models having a digital reading and a storage function to enable the user to monitor the level of gas in the house over time. Nevertheless, this type of detector is generally more expensive.
Biometric
This type uses liquids that look like human blood. In reality, it's not nearly as dangerous as it seems: The solution contains a metal-salt sugar mixture and chemical dyes that change colour when exposed to high levels of CO. It uses an infrared ray to illuminate the liquid. On the other side, a small photodiode detects the carbon monoxide. It's a safe technology but offers only a "threshold warning" when the amount of carbon dioxide is reached.
Semiconductor
In the early days of CO detection, a semiconductor system used a current to flow through tin dioxide wires. An integrated circuit monitored the process. A circuit is closed when carbon dioxide concentrations are very high. An alarm will sound. As this type requires more energy than is available from a single battery, the detector must be wired into your home. For those models that have battery backups in case power is lost, this can be a great option. Some models last as long as 10 years.
Several detectors include separate alarms that are wirelessly connected to their unit. This includes vibrating pillows that wake the sleeper in an emergency. You can also get different types of alarms such as lights or sound.
