[0002] In industrial production, construction, laboratories and other environments, toxic gases such as hydrogen sulfide, ammonia, carbon monoxide, etc. are often produced. These gases cause serious harm to human health. Therefore, it is very important to detect and alarm these toxic gases in time. In order to solve this problem, combustible and toxic gas alarm devices have emerged, but the existing devices are large in size and inconvenient to carry. For example, China has disclosed "a toxic gas monitoring and alarm device", and its application number is: "CN201020544535.2". It can automatically monitor various combustible and toxic gases through the alarm device. If the gas reaches the alarm concentration, the buzzer will sound an alarm.
