Ce blog partagera les connaissances de base sur les détecteurs de fumée et de monoxyde de carbone. Nous mentionnons également quelques conseils d'achat. Now let’s dive into the text.
How to Tell Difference Between Smoke Detector and Carbon Monoxide Detector
| Smoke Detector | Détecteur de monoxyde de carbone | |
| Function | Smoke detection, fire warning | CO monitor and warning |
| Application | House, office, school, hospital | Kitchen, fuel gas room, garage |
| Operation Principle | Monitor smoke concentration | Electrochemical reaction |
When the smoke concentration reaches a certain level, the smoke detector will alarm to remind people of the possible fire. It contains an ionization chamber. Under normal circumstances, the current and voltage in the ionization chamber are in a stable state. Cependant, if the smoke enters the ionization chamber and interferes with the normal movement of charged particles, the current and voltage will change and trigger alarm signal. Donc, it can be widely used in houses, offices, schools, hospitals and other places for the purpose of timely detection and warning of possible fire hazards.
En revanche, the main function of a carbon monoxide alarm is to monitor the concentration of carbon monoxide. It comes with a pair of special electrodes (reference electrode and measuring electrode) to detect carbon monoxide. When carbon monoxide gas enters the alarm, the measuring electrode detects its presence and converts it into an electrical signal which is proportional to the concentration of carbon monoxide. Alors, the electrical signal goes to the alarm’s microprocessor for processing. If the measured value exceeds the preset safety value, the microprocessor will alert. So, it is widely used in family kitchens, gas water heater installation, garage. In these places, the improper use of gas or equipment failure may lead to carbon monoxide leakage.
Combination Smoke and Carbon Monoxide Detector
Although the two are different, the appearance of combination smoke and carbon monoxide detector is warmly welcomed by consumers. It simplifies the use and maintenance of equipment. Users do not have to operate and maintain two independent devices, but only pay attention to just one device. De plus, the purchase of one device achieve two functions in a cost-effective way.
What Is A Smoke Detector And Carbon Monoxide Detector?
The two-in-one CO smoke alarm is a device that integrates the function of smoke alarm and carbon monoxide sensor. It combines the advantages of the two alarms. It can monitor smoke or carbon monoxide concentration, timely alarm, and remind people to take appropriate measures to protect life and property safety.
Are Combination Smoke and Carbon Monoxide Detectors Good?
Yes, they are.
- Dual Protection
The two-in-one alarm can monitor the concentration of smoke and carbon monoxide at the same time, providing double security. This means that it can alert people in the early stages of a fire or carbon monoxide poisoning so that people can take appropriate measures to reduce losses and injuries.
- Space-saving and Cost-saving
Compared to separately buying smoke alarms and carbon monoxide alarms, 2-in-1 alarms are more space and cost-efficient. It takes up the space of only one device, when avoiding the cost of purchases and installation of another one.
- Simple Use and Maintenance
Users do have to operate and maintain two independent devices, but only need to pay attention to the running status of one device. This greatly simplifies the use and maintenance, bringing convenience.
- Smart IoT Funtion
Some high-tech 2-in-1 alarms also have smart networking functions to support remote monitoring and control of smartphones. This allows users to acquire the security situation in their homes at any time and anywhere.
Will My Smoke Detector Go Off If There Is Carbon Monoxide?
Non. If there is carbon monoxide in the environment, a normal smoke detector will usually not go off. Smoke sensors are mainly used to detect smoke particles. Its alarm will be triggered only if smoke particles enter the detector and reach a certain concentration. Cependant, carbon monoxide is a colorless, inodore, non-irritating gas that differs from smoke particles. So it won’t be detected by normal smoke detectors.
Types of Smoke and Carbon Monoxide Detectors
If we make classification by working principle, there are mainly three types as follows.
- Photoinductive Smoke and Electrochemical Type
On the one hand, the concentration of carbon monoxide was measured by electrochemical principle. On the other hand, when carbon monoxide gas diffuses into the electrolyte of the sensor, a chemical reaction will occur to produce an electric current. Accordingly, the concentration of carbon monoxide is measured by amounts of the current.
- Lonic Smoke Sensing and Semiconductor Type
On the one hand, it sensors fire smoke by detecting positive and negative ions in the smoke. When smoke enters the alarm, the ion sensor detects the ions in the smoke and converts them into electrical signals, triggering the alarm.
On the other hand, it comes with semi-conductor whose materials can indirectly tell the concentration of carbon monoxide. Par exemple, when the carbon monoxide gas is in contact with the semiconductor material, the resistance value of the material is changed. So, the concentration of carbon monoxide can be calculated by measuring the change in the resistance value.
- Infrared Type
It can detect infrared radiation of smoke and convert it into an electrical signal, triggering an alarm. En plus, it can specific wavelengths of infrared light, and then identify carbon monoxide molecules whose absorption capacity is strong.
WiFi smoke and carbon monoxide detector
If you classify them by Smart IoT technologies, there are probably two mainstream categories. The first one, of course, is WiFi smoke and carbon monoxide detector. With the help of a built-in WiFi module, it does well in connecting to household wireless network. This feature enables the detector to timely transmit the data of smoke or carbon monoxide concentration to the cloud server or the user’s smartphone. Via the relative APP or web platform, users can remotely know the smoke and carbon monoxide status in the house as well as receive alerts.
In addition to the above benefits, some WiFi smoke and carbon monoxide detectors support connection with smart systems to achieve home automation. Par exemple, when the detector sends an alarm, it can automatically open the exhaust fan in the house as well as close the gas valve. This automatically reduces the harm of smoke or carbon monoxide towards human body. En plus, WiFi is very scalable. Users can increase or decrease the number of devices linked to the detector as their expectation. It’s very flexible.
The second popular one should be Zigbee smoke and carbon monoxide detector. Zigbee smoke and carbon monoxide detectors consume less power during standby and communication. This feature expand the time of endurance of the device. Typically, Zigbee devices can operate for several months or even years on just two 5 batteries, reducing the frequency of battery replacement. After all, smoke and carbon monoxide detectors are usually installed in the ceiling so installation is a bit troublesome.
Similarly, Zigbee has a wide range of compatibility and scalability like WiFi technology. This enables Zigbee smoke and carbon monoxide detectors to be linked and controlled with many other smart home devices (such as smart air purifiers, ventilation fans, etc.) for the security of the whole house.
How to Shop for Détecteur de fumée et de monoxyde de carbone
- Functions and Performance
The smoke and carbon monoxide detector should have high sensitivity. Timely and accurate detection of the concentration of CO and smoke can reduce unexpected alerts. Also, the alarm should have a variety of alarm methods, such as sound, LED indicator, and remote notification via mobile Apps, so it can effectively remind users no matter where they are. Understanding the detection coverage of the sensor is also important for suit your requirements.
- Technology and Principles
We should be clear about the detection principle used by the detector during purchasing, such as electrochemical detection or photoelectric smoke. Because different principles are applicable to different situations. If you are also considering smart home networking, we recommend Zigbee IoT to better interact with other smart household devices.
- Quality and Durability
First of all, we of course choose well-known brands and reputable manufacturers with ISO9001 certification to ensure stable product quality as well as reliable after-sales service. Et, it is generally recommended to choose products with a long life to reduce the frequency and cost of replacement.
En même temps, we should also pay attention to the material and protective functions of the detector, such as moisture, dust, and high-temperature resistance. This ensures that it can work properly in different environments.
- Cost and Price
Buyers can make comparisons among various suppliers. Understanding the market price range first avoids being misled by the trap of high or low prices. En outre, we can also negotiate with suppliers for preferential terms for bulk purchases, such as discounts, giveaways or extended warranties. Enfin, based on the product’s function, performance, quality, durability and price, we consider the cost performance of the product.
- Regulatory Certification
Don’t forget to make sure the alarm complies with local safety regulations, such as CE, UL.
- After-sales Service
