Exhibition, the mankind have found increasing toxic gas, but most common is exactly anthracemia；In family kitchen or in bath
In room, tend not to realize in time when having poison gas, the harm caused after human body suction is very big, it is therefore desirable to which one kind can be examined
Survey the alarm of toxic gas.
The content of the invention
The problem of the utility model is solves existing, proposes a kind of toxic air alarm device.
What the technical solution of the utility model was realized in：A kind of toxic air alarm device, its composition includes：Shell,
On the housing provided with one piece of liquid crystal display, in shell side provided with switch key, WIFI configuration buttons and USB chargings
Mouthful, covered with silica gel waterproof jam on the switch key, WIFI configuration buttons and the USB charging inlets, in institute
State and WIFI communication module, carbon monoxide transducer, temperature/humidity sensor, buzzer, lithium battery, main control MCU are provided with shell
System.
The shell four corners below is provided with 4 fixed screws, two sucker fixed screw posts, air-vent and waterproof and breathable
Film.
The WIFI communication module, carbon monoxide transducer, temperature/humidity sensor, buzzer, liquid crystal display, buzzer
It is connected with main control MCU system, the lithium battery provides electric power, is also set up between the lithium battery and the main control MCU system
Lithium electric protection module and management of charging and discharging module.
The beneficial effects of the utility model are：The utility model structure is attractive in appearance, small volume, can be aobvious by the liquid crystal display moment
Show that the concentration of toxic gas in air again can be by buzzer warning；5V is first raised to using by lithium battery voltage, by low
Power consumption, the power supply plan of low voltage difference LDO voltage stabilizings to 3.3V, that is, ensure the steady operation of wifi module and sensor conversion circuit,
It make use of electric quantity of lithium battery to greatest extent again, extend single charge service life.
