1. dc-battery and 220V AC powers can all drive the utility model to be operated.

2. MUC is passed through（Single-chip microcomputer）System controls sensor assembly so as to which detection is presently in the air under environment The concentration signal of various gases, returns again to MUC (single-chip microcomputer) and is processed these signals.

3., simultaneously by Single-chip Controlling information transfer to display, display detects the concrete concentration of gas；While by Single-chip Controlling information judges whether to early warning；If indoor mode：Buzzer works simultaneously with filter vat；If outdoor mould Formula：Gsm module control system sends information to a range of mobile phone of periphery and relevant department；Believed by Single-chip Controlling simultaneously Breath is stored in instrument, calling after convenience；Simultaneously by Single-chip Controlling air pump, each two hour carries out a length of a when time The blowback of 5 seconds, realizes self-cleaning.

Practical beneficial effect of the present utility model is mainly manifested in：It is divided into two kinds of use patterns of indoor and outdoors, can meets The monitoring of current environment needs；Indoor early warning is buzzer, and outdoor early warning is gsm module, can remind the matter of people's present air Amount quality；2. filter vat may filter that particulate matter larger in air and insect etc.；Instrument work certain hour after, air pump The blowback of 5 seconds can be carried out, strengthens device longevity.

Description of the drawings

Fig. 1 is outward appearance conceptual schematic view of the present utility model.

Fig. 2 is conceptual design schematic diagram of the present utility model.

In figure, 1, detector main body, 2, detection zone device, 3, alarm, 4, filter vat, 5, flowmeter, 6, air Pump, 7, Temperature Humidity Sensor, 8, valve, 9, air admission hole.

Specific embodiment

As shown in Figure 1；After instrument is started working, first air pump 6 pumps into quantitative air sample from air admission hole 9, connects Air sample and sequentially pass through detection zone device 2, filter vat 4, flowmeter 5, air pump 6, finally discharge from valve 8.

Detection zone device 2 is by MCU（Single-chip microcomputer）With temperature and relative humidity, PM2.5 sensors, TVOC sensors, dioxy Change carbon sensor, ozone sensor, nitrogen dioxide to constitute, MCU（Single-chip microcomputer）The particulate in air that sensor is monitored Concentration be analyzed, and by the data for obtaining graduation include in LCD（LCDs）On, while according to instant AQI（It is empty Makings volume index）User is pointed out accordingly or alerted.As shown in Figure 2.

When instrument is in outdoor environment working condition, the single-chip microcomputer and PM2.5 sensors of detection zone, ozone sensor, two Nitrogen oxide working sensor, then have following four kinds of situations：

If AQI（Air quality index）In outstanding scope, LCD then shows that " the currently monitored air quality is good, and household Friend goes together outdoor activity ".

If AQI（Air quality index）In normal range (NR), LCD then shows that " the currently monitored air quality is up to standard, Ke Yifang The heart is gone out ".

If AQI（Air quality index）In poor scope, LCD then shows that " the currently monitored air quality is poor, please carry Mouth mask is gone out ".

If AQI（Air quality index）In severe overweight scope, LCD then shows that " the currently monitored air quality seriously surpasses Mark, it is not recommended that you are to open air ".Now instrument sends note by gsm module to user, points out air quality relatively low.

When instrument is in indoor environment working condition, detection zone is sensed by Single-chip Controlling carbon dioxide sensor, VOTC Device, temperature sensor, humidity sensor are operated, then have following three situation：

If AQI（Air quality index）In normal range (NR), then " IAQ is up to standard " is shown.Buzzer not work Make.

If AQI（Air quality index）In relatively low scope, then " IAQ is relatively low, please divulges information in time " is shown.

If AQI（Air quality index）In severe overweight scope, then show " IAQ severe overweight, it is uncomfortable Preferably continue to stop indoors ", while alarm buzzer work.

While switching with outdoor both of which indoors, different sensors also can switch therewith, alternation.

It is to for protecting air pump and sensor, filter out particulate matter larger in air and insect to install filter vat Deng to protect air pump, prolongation device longevity.

Flowmeter measures the volume of the air sample for pumping into, speed and time that indirect control air sample is pumped into.

After air sample collection terminates, air pump can carry out the blowback of 5 seconds, it is therefore an objective to clean sensor and protection Air pump, extends device longevity.
