Reason module includes microcontroller and analog-digital converter；The data disaply moudle includes display screen；The dust sensor and numeral
Wet temperature sensor is electrically connected with analog-digital converter；The analog-digital converter is electrically connected with microcontroller；The microcontroller
It is electrically connected with display screen.
Air environment monitoring device of the present invention, the microcontroller are 8 microcontrollers；8KB Flash memories；32
I/O mouthfuls.
Air environment monitoring device of the present invention, house dog and timer built in the microcontroller.
Air environment monitoring device of the present invention, the microcontroller are STC89C52RC microcontrollers.
Air environment monitoring device of the present invention, the dust sensor are GCG1000 dust sensors.
Air environment monitoring device of the present invention, the wet temperature sensor are DHT11 Temperature Humidity Sensors.
Air environment monitoring device of the present invention, the display are the LCD12894 displays with character library.
Air environment monitoring device of the present invention, passes through data acquisition module, the data processing mould being sequentially connected electrically
Block and data disaply moudle, realize to the PM2.5 of air quality collection, calculate, display function, have that circuit is simple, cost
It is low, high certainty of measurement, it is highly practical the characteristics of, and simple in structure, easily operated use, suitable for promoting and applying.
Embodiment
Air environment monitoring device of the present invention, including data acquisition module, the data processing mould being sequentially connected electrically
Block and data disaply moudle；The data acquisition module includes dust sensor and digital wet temperature sensor；At the data
Reason module includes microcontroller and analog-digital converter；The data disaply moudle includes display screen；The dust sensor and numeral
Wet temperature sensor is electrically connected with analog-digital converter；The analog-digital converter is electrically connected with microcontroller；The microcontroller
It is electrically connected with display screen.
Embodiment one
Using the STC series monolithics of macrocrystalline company production as data processor.STC89C52RC series monolithics are preceding
The microcontroller that a quick, performance produced on the basis of 51 series monolithic of a generation is stablized.Its Embedded 8KB program storages
Device, band house dog and three timers are quick, conveniently using TTL cold start-up programming programs.Working frequency is high, anti-interference, difficult
Decryption.Relative in the market, other microcontroller prices are lower, have to the singlechip controller material for developing small utility in a short time
Very strong advantage.Using GCG1000 dust sensors, which can use in containing the quick-fried dangerous mine of gas or dirt, energy
Adapt to various adverse circumstances.Using integrated form CD-HTD-3107 Temperature Humidity Sensors, although the product accuracy of measurement is relatively
Height, measurement data are relatively stablized, but the response time is grown, and construction is complicated, should not work for a long time under high humidity environment.Using band word
The LCD12864 in storehouse is shown as output.Advantage：Display content is more, can preferably show image, itself band character library, beneficial to volume
Journey.Shortcoming：Volume is larger, and programming is more complicated and price is high.Using AD7705.The chip uses the ADC of sigma-delta, realizes
16 superperformances without error code, programmable amplifier can set input signal gain in piece.In+3V power supplys and 1MHz master clocks
When, AD7705 power consumptions are only 1mW.Power consumption is extremely low, meets environmentally protective theory.Applied to microprocessor（MCU）, at digital signal
Reason（DSP）System tool have great advantage, shortcoming be it is expensive, it is higher to circuit requirement.
Embodiment two
Using STM32 as control and data processor.Although STM32 is dominant in data transfer and processing, phase is programmed
To more complicated.Using dust sensor .GP2Yl010AUOF, the sensor is small, and low in energy consumption, program is simple, with microcontroller
Connection circuit easily build, it is cheap the advantages that.Using digital DHT11. wet temperature sensors, sensor output is interior
The calibrated digital signal in portion, has the advantages that response time is fast, and strong antijamming capability is small, and interface is simple.Using
LCD1602 is shown as output.Advantage：Show that program is fairly simple, volume is little, cheap.Shortcoming：Show information content
It is small, it is impossible to show image.Using cheap ADC0832 chips.0~5V of the chip operating voltage section, working frequency
250kHz, binary channels change 8 bit resolutions, and operating temperature range is wide, volume very little and compatibility is strong.It can meet conventional
Analog/digital conversion circuit requirement.
