With the widespread use of city gas, accidents such as explosions, poisoning, and fires caused by gas leaks are common. In confined spaces, natural gas is flammable and explosive when mixed with air. When the concentration of natural gas in the air reaches 5%-15%, it can explode when exposed to open flames. Therefore, preventing natural gas leaks is crucial.

    When a gas leak occurs in a home, a gas alarm detects the leak and sounds an alarm. This signal is also transmitted to an emergency shut-off device, which automatically and quickly closes the main gas supply valve, cutting off the gas supply. This significantly reduces the incidence of gas accidents and protects users' personal and property safety.

    Gas alarms prevent gas explosion hazards based on three key principles: early detection, timely warning, and emergency response. When the detected gas concentration reaches the set lower explosion limit, or warning value, the gas alarm issues an alarm signal, alerting the user to take timely safety measures and prevent a gas explosion.

    As the core component of a gas alarm, semiconductor gas sensors play a crucial role. Tensensor recommends the following products:

MQ-K4 Semiconductor Natural Gas Sensor

MQ-D4B Flat semiconductor sensor

    Semiconductor gas sensors can be used not only for combustible gas detection, but also for the detection of smoke, alcohol, carbon monoxide, ozone, ammonia, hydrogen sulfide, organic vapor and other gases. Tengxing Sensing semiconductor series gas sensors include civilian semiconductor series and industrial-grade semiconductor series.
