APPLICATION

Home Combustible Gas Alarm

The combustible gas alarm is an alarm device for detecting gas leakage. The component that reacts to the combustible gas is a gas sensor, and the response signal is converted into an electrical signal through the circuit board. When the combustible gas in the air reaches a certain concentration value, the alarm will alarm. The high-end household combustible gas alarm can automatically start the exhaust equipment and close the gas pipeline valve at the same time. A wireless transmission device can be installed inside the gas alarm to realize overall monitoring and network alarm to ensure the safety of everyone's life and property.
