Things to Know About Propane Detector

What is a gas detector?

A gas detector (or gas sensor) is a device that detects the presence of one or more types of gas in an environment. As part of the home security system, a gas detector is an appliance that has the sole function of guaranteeing the quality of the air by constantly measuring the degree of toxicity of the surrounding environment.

A small distraction such as the gas stove on or falling asleep forgetting the fireplace or the natural gas stove in operation could cause potentially fatal accidents.

In fact, we report that, according to data collected by the ministry of health, about 500-600 people die every year due to carbon monoxide poisoning. A gas detector is, therefore, a tool that can really make a difference in terms of security in your home.

Most detectors produce an acoustic or visual signal, such as an alarm or a series of lights in the event that dangerous or potentially life-threatening gases are detected. In the past these devices were able to detect only one type of gas; today it is possible to find multifunctional models on the market capable of detecting more types of substances in the air and therefore guaranteeing greater home security.

These devices function as independent units(therefore without the support of a computer) and therefore used to monitor small environments, or they can be connected together to create an entire protection system based on the nature and size of the area we want to monitor.

Recall that a gas detector can make a huge difference in terms of safety, regardless of the type of environment in which it is installed, whether it is an apartment, an office or a mechanical workshop.

What Harmful Gases?

Smoke gas detector worries too much about external dangers and underestimates those inside our homes. In the European directive 89/106 of 21 December 1988 the following pollutants related to harmful emissions inside a building are listed :

  • Metabolic Products (water vapor, carbon dioxide, bad smells);
  • Combustion Products (carbon monoxide, nitrogen oxides, carbon dioxide, hydrocarbons, etc.);
  • Volatile Organic Compounds (formaldehyde, organic solvents, etc.);
  • Microorganisms such as small insects, protozoa, fungi, bacteria, and viruses;
  • Radon is any type of radioactive substance that emits gamma radiation;
  • Emissions from electrical and electronic equipment.

Some of these pollutants can be very harmful, even fatal, if not immediately detected in the air. For example, carbon monoxide (co), not to be confused with carbon dioxide (co2), is an invisible, odorless and tasteless gas that is extremely toxic to humans and animals.

It is often called the “silent killer” because it is not perceptible through the senses: we can neither smell it, nor taste it, nor see it. The initial symptoms of carbon monoxide poisoning, tiredness, and headache are similar to those of the flu, which can make it difficult to make a diagnosis.

If there are deadly levels of carbon monoxide in a house, the inhabitants will not notice it and will not wake up. The longer this gas is inhaled, the worse the symptoms become, including loss of balance, loss of vision and memory, and ultimately loss of consciousness.

Also gas, LPG or methane, which can cause explosions, is used in most homes to power stoves, heating systems, and kitchens, for which it represents a concrete danger not to be underestimated.

To prevent this type of accident it is possible to install a gas detector for home safety, which warns of any leaks or other types of emergencies by means of acoustic or light signaling. The most advanced models are able to detect multiple types of gas at the same time.


Security gas detector these devices are generally very simple and intuitive mainly for one reason: they must manage, through a minimal interface, to be clear and easy to read if you are in a dangerous situation.

The devices on the market communicate the state of domestic pollution mainly in two ways: with sound signals or with visual signals (many models are capable of emitting both signals).

The auditory alarm generally consists of an intermittent sound with an intensity of about 85 decibels, a sufficiently high volume that allows the signal to be heard even by neighbors.

As for visual cues, these devices are often equipped with lights or led displays which, in the most advanced models, are able to show the type and level of pollutants.

The LEDs also indicate the operating status of the device: it is, in fact, important to be able to count on a device that is always functional.

The different colors of the LEDs have the task of signaling multiple information, including the correct functioning of the device or the exhaustion of the battery in the case of a model not connected to the household electric current.

Some models have pre-alarm systems that detect even the smallest amount of polluting gas and warn of possible imminent dangers (this is the case, for example, with smoke detectors).


The installation of these devices is very simple, however, it is good to pay attention to a few steps necessary to ensure correct operation. Here are some tips that could come in handy if you decide to install the gas detector yourself. In case of difficulty, we advise you to contact a professional.

The gas detector must not be placed near air intakes, fans, air outlets of air conditioning systems, or in areas with high humidity or escaping vapors (for example in the bathroom);

Pay attention to any substances present in the environment that can alter the sensitivity of the detector (such as silicones or hydrogen sulfide). If you suspect the presence of these substances, you should consult an expert;

The detector must be placed in easily accessible places that allow reading and maintenance operations;

The ideal location for the methane gas detector is the ceiling, at a hob, about 30 centimeters from the ceiling, since methane gas, being lighter than air, tends to thicken upwards.

In the case of an LPG gas detector and other heavier gases, the sensor must be installed about 30 centimeters from the floor since the pollutants will disperse in the lower part of the chamber to be monitored.

Carbon monoxide has a specific gravity almost equal to that of air, which is why the exact height where the gas is deposited is not detectable; in this case, the detector can, therefore, be installed at a height of about 1.50 meters from the floor.

As for the power supply, some of these products can be connected to the electric current, while others have rechargeable batteries (via USB cable or by connecting the device directly to the power outlet).

It is very important that the device can report a low battery level so that you can recharge the device before it stops working. Feed gas detector


Some gas detectors, generally the more expensive and advanced models, have features and functions that facilitate the reading of the data collected by the device. Let us now illustrate some of the most useful and innovative features:

  1. Vocal Interface: some devices give the possibility to interact with them through vocal commands, a feature that could prove very useful for the blind;
  2. Night Light: some gas detectors emit a soft light which, in addition to signaling the correct functioning of the device, could reconcile sleep or help you orient yourself in the dark;
  3. Battery Warning: an led or display indicates the battery status. It is essential that the gas detector is always in operation in order to guarantee safety in the home;
  4. Smart Detectors: you can connect them to the home network and associate the device with your smartphone so that you can receive notifications whenever the alarm is triggered, when the batteries are running low or when a sensor is not working properly.

How to Use a Gas Detector?

The gas detector is a device that can save your life, whether you use gas only for cooking, or you rely on the combustion of the same to heat your apartment.

The Home Risks

the risks at home are often underestimated, usually greater than those in other situations. In fact, when you are inside your home, you tend to drop your guard, paying little attention to crucial elements.

When there are many in the family, it is certainly easier to notice if there is something wrong, however, for those who live alone, especially the elderly, it may not be so simple.

Dangerous Distractions

A small distraction could lead to forgetting the gas burners, with continuous delivery, or falling asleep forgetting a running natural gas stove, thus generating potentially fatal accidents.

The purchase of a gas detector could, therefore, make you sleep soundly. So let’s see how best to use such a device.

Types of Gas

first of all, make sure that the types of gas detected are as high as possible. So don’t stop at the simple methane detector but opt ​​for products that can also recognize propane or butane leaks.

Once you have chosen the best device for your needs, you will have to install it. We remind you that, if you have no experience, it would be better to rely on the expert hands of a professional. In fact, when dealing with security systems, economic savings should go into the background.

Choose the Location

The ideal position should, therefore, be chosen, about half a meter from the ceiling. The standard detectors must be fixed to the wall by means of screws and support supplied inside the package.

To work they must then hook up to the electricity, so don’t forget to purchase an extension if you don’t have an electrical outlet near the place chosen for the installation.

Power On

After fixing it to the wall, you can insert the plug into the socket and check whether the indicator light indicating that the device is switched on is active. If yes, the product is ready for use.

if it detects a harmful gas in the air it will emit an intense and immediately recognizable sound signal to warn those in the house.

If the light is not on, we invite you to first check the operation of any extensions used, and then carefully leaf through the instruction manual supplied with the product. In this way, you will be able to understand if it is necessary to carry out a specific procedure before operating the detector.


Some small measures consist not placing the detector near ventilation systems or air intakes since the concentration of gas in those areas could be significantly lower than that of the environment, thus returning a false negative and I threaten the occupants.
