Carbon monoxide (CO) is a colorless, odorless and non-irritating gas, but it has serious harm to human health. Usually carbon monoxide (CO) Incomplete combustion of carbonaceous materials. Carbon monoxide in the indoor environment mainly comes from cigarettes, heating equipment and kitchen. A cigarette usually produces about13mgCarbon monoxide, for high breathability cigarette paper, can promote the complete combustion of cigarettes, the amount of carbon monoxide produced will be relatively small. Carbon monoxide produced by heating equipment and kitchens is mainly caused by incomplete combustion of fuel.

The following isCOThe hazards:

Poisoning:COThe explosion limit concentration12.5%Excessive human inhalationCO，COIt combines with hemoglobin to form carboxyhemoglobin, which blocks the blood's ability to carry oxygen. high concentrationCOCan lead to poisoning, causing headache, dizziness, nausea, vomiting, confusion, coma and even death.

Effects on the cardiovascular system:COPoisoning can cause insufficient oxygen supply in the blood, increase the burden on the heart, and increase the risk of heart disease, angina and myocardial infarction.

Effects on the nervous system: long-term exposure to low concentrationsCOIt can also have a negative impact on the nervous system, leading to headaches, memory loss, inattention, and mood changes.

In order to preventCOPoisoning, let the family rest assured, in easy to produceCOThe environment should be installed and checked regularly.COAlarm, especially in confined spaces such as homes and shopping malls. In hererecommend you two semiconductor sensorsTGS5042-A00，TGS5141-P00. Suitable for residential and commercial carbon monoxide detector, industrial carbon monoxide monitoring, indoor parking lot ventilation control, fire alarm and other scenes, thenTGS5042-A00，TGS5141-P00What's the difference?

TGS5042 is a battery-driven electrochemical sensor developed by Figaro. Compared with existing electrochemical sensors, it has the following advantages: the electrolyte is environmentally friendly; there is no danger of electrolyte leakage; carbon monoxide can be detected at concentrations up1%Wide operating temperature range (-5˚C ~ 55˚C); Very low sensitivity to interfering gases. This kind of sensor has the characteristics of long service life, good long-term stability and high precision. It is one of the few ideal sensors for digital display.

TGS5141 is a battery-driven electrochemical sensor developed by Figaro that uses a special electrode instead of the water reservoir.TGS5042The water reservoir used in,TGS5141withTGS5042Compared with the latter, its external size is reduced to only the latter.10%Size. The ultra-small size makes it an ideal choice for portable carbon monoxide detectors, miniature residential carbon monoxide detectors, and multi-purpose fire detectors.

The following are the specific specifications of the two sensors. Please consult for details。
