[0002] In order to ensure the air quality inside the shopping mall and provide early warning and protection in the event of a fire, corresponding alarm sensors are required. A patent for a gas sensor and a gas alarm is currently available, and the patent publication number is CN201397315Y. This utility model relates to a gas sensor and a gas alarm. The gas sensor includes: a substrate; a gas-sensitive element for converting a gas concentration signal into an electrical signal; a micro-smoke sensor for converting the electrical signal into a number of control signals for controlling a number of external devices; a number of pins for outputting control signals; a voltage stabilizing device for converting an input voltage into a preset voltage; a pin for inputting an input voltage; a pin for outputting a preset voltage; a pin for connecting to a power ground; and a pin for triggering the micro-smoke sensor to perform basic function detection. This utility model integrates various components on a single substrate by placing the gas-sensitive element, the voltage stabilizing device, and various pins on the substrate, and uniformly controlling them through the micro-smoke sensor placed inside the substrate.
