Description
Technical field
The present invention relates to Smart Home, particularly to finely ground particles content Monitoring and Controlling in indoor air environment.
Background technology
Chinese Urbanization's and industrialized fast development increase sharply with energy resource consumption, bring much to Chinese city
Air pollution problems inherent, urban air pollution affects the health of urbanite and the development in city.Along with people's living standard
Improve constantly, healthy attention rate is the most gradually deepened, and in the Internet+epoch, a can real-time perception empty
The product of makings amount is urgently developed.
In current dust granules PM2.5 detection field, main use two kinds of dust sensors: infrared dust sensor and
Laser dust sensor.Structure and the circuit of infrared principles dust sensor are fairly simple.Its light source is infrared LED light source, gas
Flow into or out air port mainly by resistance heating to obtain thermal current flowing, have granule to pass through i.e. and export high level.Output signal is only
PWM model.And the structure of laser sensor and circuit are relative complex.Its light source is laser diode, and sampled air passes through fan
Or aerator promotes, by the air channel of somewhat complex design, detect.When the fine particle in air enters laser beam region
Time, laser will be made to scatter；Scattered light has radiation in 360 ° of space, and we in position place photodetector, make
Only receive scattered light, be then passed through photodetector photoelectric effect produce current signal, through circuit amplify and process after, i.e.
Available fine particle concentration value, output signal is generally serial ports output.
Infrared principles dust sensor is only able to detect the granule of more than 1um, and certainty of measurement is not enough.Because infrared LED light
The particle signal of scattering is more weak, only has a response to the bulky grain more than 1um, and the most only promotes sampling gas with adding thermal resistance
Stream, hits is less, and data calculate transfers to host computer to carry out completely.And laser dust sensor can detect more than 0.3um
Granule.Because carrying high-performance CPU, using fan or aerator to gather mass data, dividing via specialty grain count algorithm
Analysis；To sum up, at hits, data source, algorithm three aspect all than infrared dust sensor advantageously.
Owing to precision is not enough, infrared principles sensor is mainly used in industrial and mineral airborne dust, and detection object is big particle diameter, high concentration powder
Dirt, detection rank is mg/m3, it is impossible to accurately measure the concentration of PM2.5.And Principles of Laser sensor is mainly used in PM2.5 inspection
Survey field, with accuracy quantification PM2.5 mass.Can be embedded in domestic (vehicle-mounted, hand-held) air detection instrument, air purifier.This
Outward, Principles of Laser sensor also has application in fields such as internet of things data acquisition, environmental quality detections.
