Description
Technical field
The utility model relates to field of gas detection more particularly to smoke from cigarette detection field, in particular to a kind of realizations
The circuit device of smoke from cigarette double check function.
Background technique
PM2.5 sensor is also dust sensor, dust sensor, can be used to detect the dust in our surrounding airs
Concentration, i.e. PM2.5 value size.The dust that diameter can enter alveolar region less than 10 μm is also commonly referred to as respiratory by aerodynamics
Dust.Diameter largely passes through shock deposition in 10 μm or more of grit, is largely deposited on pharynx nasalis in human body sucking, and
10 μm of dust below can enter the deep of respiratory tract.And the dust deposited in alveolar is largely 5 μm of dust below.
PM10 then refers to particulate matter of the aerodynamics equivalent diameter less than or equal to 10 μm in surrounding air.PM2.5 thin
Grain object diameter is small, and the time to suspend in an atmosphere is long, and the distance of Spreading and diffusion is remote, and usually contains a large amount of poisonous and hazardous objects
Matter, thus it is bigger to Health Impact, and PM2.5 can enter lung, blood, if very big danger can be had to human body by carrying the germs of a disease
Evil, including respiratory system, cardiovascular system, the even reproductive system to us.
The working principle of 2.5 dust sensor of PM is developed according to the scattering principle of light, and particle and molecule are in light
The lower scattering phenomenon that can generate light of irradiation also absorbs the energy of partial illumination light at the same time.When a branch of collimated monochromatic ligth is incident
When to tested particle field, the influence for scattering and absorbing around particle will receive, light intensity will be attenuated.Can thus acquire into
Penetrate relative attenuation rate of the light by concentration field to be measured.And the size of relative attenuation rate substantially can linear response field dust to be measured
Relative concentration.The size of light intensity is directly proportional with the electric signal power through photoelectric conversion, can be in the hope of phase by measuring electric signal
To attenuation rate, and then the concentration of dust in field to be measured can be measured.
2.5 sensor of PM is designed to the dust particle in induction air, and interior diagonal places infrared light emission
Diode and phototransistor, their optical axis intersection, when the intersection region that the air-flow with dust is intersected by optical axis, dust pair
The light intensity of infrared light reflection, reflection is directly proportional to dust concentration.Phototransistor is so as to which to detect dust in air anti-
Light is penetrated, can be detected the very tiny particle such as tobacco smoke, infrared light-emitting diode is launched light and encountered
Dust generates reflected light, and receiving sensor detects that the light intensity of reflected light, output signal are sentenced according to the size of output signal light intensity
Disconnected dust concentration distinguishes the concentration of different dust particles by two different pulse-width signals (PWM) of output.
In the environment of our normal lifves, the concentration of the dust or aerosol of PM10 and following size is divided into, well,
Difference, very poor etc., good standard is PM lower than 50 milligrams every cubic metre, and well between 50 to 100, difference generally refers to 100 and arrives
It is just very poor more than 200 between 200.When more than 200, most people can be felt like a hen on a hot girdle.The diameter of smoke from cigarette particle is most
At 0.1 to 1.0 micron, so public place smoking ban.
In the prior art, when being detected to smoke from cigarette, it will usually using the detection mode of PM sensor, PM sensor
With filtering function, common dust, water vapour can be filtered out, partial size all in the particle of 2.5um or more, reduces rate of false alarm, mentions
High PM detects smoke from cigarette accuracy, however, even if PM sensor uses the function of filtering out common dust granule, but current
Environment is complex, when having other more interference factors, what the simple detection for carrying out smoke from cigarette using PM sensor obtained
Testing result is also inaccuracy.
