Carbon monoxide is a gas that poses a significant threat to human life. It is odorless, colorless, and lighter than air. Its presence can only be detected using special carbon monoxide sensors. For this type of protection to function properly, the entire gas detection system must meet certain conditions. Read our guide on the subject and read how to minimize the risk of carbon monoxide poisoning!
From the article you will learn:
- what conditions must the gas detection system meet,
- how to minimize the risk of carbon monoxide poisoning,
- where to install carbon monoxide detectors.
Gas sensor as a key element of every detector
Gas detection can be handled by advanced detection systems or independent sensors, including gas detectors . In the first case, in a dangerous situation, the system triggers an alarm and informs the building owner, its manager or the company responsible for its safety via a mobile application. In the second case, the device only sends local sound signals, warning against too high a concentration of carbon monoxide in the air.

In both cases, carbon monoxide sensors play the main role. These are small devices, the key element of which is the gas sensor . Four types of such sensors are used in electronic detectors:
- Electrochemical - cells that generate electric current. Its intensity is proportional to the concentration of gas penetrating the electrolyte. Sensors of this type are most often used to detect toxic gases.
- Catalytic - contain an active and passive element with identical resistance at the same temperature. Under the influence of a flammable gas, the oxidation reaction occurs only on the active element. As a result, heat is released and a voltage appears in the system, which informs about the exact value of the gas concentration.
- Infra-Red - using the phenomenon of absorption of infrared radiation by chemical bonds of gas molecules. These sensors are usually used for precise measurements of carbon dioxide, propane and butane concentrations.
- Semiconductor - based on the phenomenon of surface adsorption of gas on the measuring element. In the event of detection of a threat, the resistance of the semiconductor changes, related to the concentration of a given gas in the air. Sensors of this type are used in threshold detectors, and their most perfect form are carbon monoxide sensors.
The selection of appropriate sensors is determined by the conditions prevailing in the facility and the required precision of measurements. Only by taking into account these criteria will the detectors function properly and meet the expectations of users.
What to pay attention to when installing gas detectors?
To ensure that the detection system operates correctly, 4 basic conditions must be met:
1. Proper selection of equipment
When selecting gas sensors, it is necessary to take into account the temperature and humidity of the air , as well as the presence of gases that interfere with the measurements. Depending on the needs of users, it is also necessary to consider aspects such as the method of visualizing and archiving data and the possible need to control executive devices and use emergency power supply. When selecting devices for the conditions in a given building, the correct setting of alarm thresholds will be a very important issue - remember that too low a level may trigger unnecessary warnings and disrupt the proper functioning of the facility.
2. Installing sensors in appropriate locations
The detector will only monitor gas concentration correctly if it is installed in the right place. Therefore, remember to place the devices where the gas may accumulate. You need to consider, among other things , its weight, as well as the movement of air in individual rooms (e.g. the presence of exhaust and supply vents). Remember to ensure easy access to each sensor.
3. Correct installation
As with any other electronic installation, gas sensors should be connected in accordance with the instructions and using the appropriate mounting materials . Make sure that the wiring is done carefully and in accordance with applicable regulations.
4. Proper operation of the system
The measurement of gas concentration will be reliable only in the case of proper use of the entire system. It is therefore necessary to follow the rules specified in the operating instructions and carry out checks and calibrations at the recommended times . Remember that the sensor sensor can only be adjusted by authorized laboratories under conditions specified by the manufacturer.

How to Minimize the Risk of Carbon Monoxide Poisoning? Rules Every Installer Should Communicate
A gas sensor in each of the strategic rooms of the building is a guarantee of safety and protection against carbon monoxide. It is worth being aware of where this threat comes from. Installers of carbon monoxide detectors should always communicate the principles that can be used to minimize the risk of poisoning. So what should you remember?
- Regular technical inspections of heating and ventilation installations and checks of chimney patency.
- Modernization of outdated heating devices - replacement of equipment with devices equipped with the necessary protection and sensors.
- Proper ventilation of rooms where boilers are located.
- Installation of a professional gas and carbon monoxide sensor or an entire detection system.
It is also worth educating people about what causes carbon monoxide to appear in the air and how to react if it is detected. The installer should therefore remind them that high carbon monoxide concentrations are caused by fires, leaks in gas and coal stoves, backflow of exhaust fumes from chimneys and poorly functioning ventilation .
When the detector detects danger during the measurement of carbon monoxide concentration, an appropriate sound signal will sound. In such cases, it is best to leave the building and call for help . In such cases, you should not enter the boiler room, because the level of carbon monoxide in the air there can be very high.
