Carbon Monoxide Sensors
How does an alarm system detect carbon monoxide if it’s a colorless and odorless gas? Which kind of carbon monoxide alarm system is appropriate for your home? Read on to learn more about the answers to these questions.
Electrochemical Carbon Monoxide Alarm System
The electrochemical carbon monoxide alarm system contains a chamber. Platinum and acid are substances that are inside the chamber. These substances break down carbon monoxide when it enters the chamber. Carbon monoxide breakdown causes the substances to release electrons. An alarm will be activated when the electrons produce an electrical current.
According to the best home security system consumer reports, it’s typically battery-powered. It’s accurate but can be susceptible to contamination overtime if not well-maintained. It’s usually expensive and its life expectancy is 2-5 years if you don’t change its sensor every two years or so.
The electrochemical carbon monoxide alarm system needs to have its battery changed periodically. It may also need its covering to be changed when its battery is consumed. It can also detect extremely low levels of carbon monoxide.
A memory feature may come with the electrochemical carbon monoxide alarm system. The memory feature records the maximum carbon monoxide levels. The memory feature also allows you to use a digital readout to check the maximum carbon monoxide levels.
Semi-conductor Carbon Monoxide Alarm System
The semi-conductor carbon monoxide alarm system typically has a 10-year life expectancy or more. The best home security system consumer reports claim that it does not detect gases other than carbon monoxide. It has a chamber that contains tin dioxide.
A small electrical current heats the tin dioxide when carbon monoxide is detected. The detection of carbon monoxide sets off an alarm. Electrons are released when the heated tin dioxide breaks down the carbon monoxide. The electrons and the broken down carbon monoxide are absorbed by the heated tin dioxide.
The semi-conductor carbon monoxide alarm system needs to be plugged into a wall outlet. This is because it requires more energy than other carbon monoxide alarm systems. High humidity levels may deteriorate it. A false alarm may be generated if it detects common household chemicals.
Biomimetic Carbon Monoxide Alarm System
The biomimetic carbon monoxide sensor may have a battery that needs to be replaced periodically. It contains a gel-coated disc that detects carbon monoxide. The gel-coated disc will set off an alarm and turn dark if a dangerous level of carbon monoxide is detected.
According to the best home security system consumer reports, it requires less energy. It’s also cheaper than other carbon monoxide alarm systems.
The biomimetic carbon monoxide alarm system may set a false alarm. This will happen if it’s affected by excessively low or high temperatures. It may set a false alarm if it’s affected by too much humid. A false alarm may also occur when it accumulates carbon monoxide and other gases overtime.
The best home security system consumer reports claim that you must purchase a carbon monoxide alarm system. This is because it prevents you from acquiring carbon monoxide poisoning.
