Embodiment
In order to further appreciate that the invention, features and effects of the utility model, and attached drawing is coordinated to describe in detail such as
Under.
The structure of the utility model is explained in detail below in conjunction with the accompanying drawings.
As shown in Figure 1 and Figure 2, the house security warning device that the utility model embodiment provides includes：Microcontroller 1, human body
Induction heat releases infrared sensor 2, smoke sensor device 3, GSM mobile communication modules 4, audible-visual annunciator 5, gas sensor 6, LCD
Display 7.
Human body sensing heat releases infrared sensor 2, smoke sensor device 3, GSM mobile communication modules 4, audible-visual annunciator 5, coal gas
