In recent years, natural gas has entered thousands of households. Gas stoves and gas water heaters are also widely used, which brings convenience to residents' lives. At the same time, gas leakage and explosion accidents occur from time to time.

At about 14:53 on October 9, 2023, a gas explosion occurred at No. 998 Jiukeshu Middle Road, Liyuan Town, Tongzhou District, Beijing, causing 1 death and 16 injuries, with a direct economic loss of 3.6707 million yuan.

The main cause of the accident is that after the employees dismantled the blind plate of the natural gas pipeline without permission, the gas in the natural gas pipeline was released in violation of regulations, resulting in continuous leakage of natural gas, spread to the kitchen and adjacent stores, and mixed with air to reach the explosion limit concentration. In the kitchen, electric sparks exploded, resulting in accidents.

After the interview with nearby residents, the residents reported that they smelled a peculiar smell, but they did not know it was the smell of natural gas, which shows that we ordinary people also need to use gas detectors or gas alarms. After all, gas is usually colorless and tasteless, under normal circumstances we are unable to detect the leak, there is a smell is the gas company added odorant，People who are not familiar with the smell can not make the correct distinction, the gas sensor is very good to detect combustible gas.

The main component of natural gas is methane, which is a combustible gas. When the gas concentration in a confined space reaches a certain concentration, it will explode when encountering an open flame. When the gas is not fully burned, carbon monoxide is also released. Therefore, the safety of gas is very important. In hereTo recommend a semiconductor sensor TGS2619-C00. It has high sensitivity to methane gas, because of its low sensitivity to volatile alcohol (common interference gas in living environment), it is an ideal sensor for household gas leak alarm.

There is also a TGS2619-E00, which is equipped with a filter cover that can eliminate the influence of interference gases such as alcohol on the basis of the original TGS2619-C00, and has the sensitive characteristics of extremely high selectivity to methane gas. Especially suitable for complex atmosphere, demanding household environment for testing appliances, is the ideal household gas leak detector sensor. Suitable for household gas leak alarms, portable gas detectors, and leak detection of gas facilities.
