【正文】 data acquisition more plays an important role, the sensor can be said to be the core content of environmental data collection, no sensors involved, there is no data acquisition. In today39。s society, environmental data acquisition in modern industry and people39。s daily life are important to the development of science and technology, it is a prehensive result, in more and more fields play an important role, such as the emerging concept of working, it is the use of sensor data collection. Object parameters, coupled with wireless technology, it can be a lot of information of the objects are connected into a work. Data acquisition of diversification, the convenience and accuracy is always thinking hard exploration and humidity sensor application is in such cases emerge as the times require. Agricultural greenhouse production, storage management, weather forecast, daily life and scientific research on temperature, humidity requirement is very important. However, cable connection often has serious limitations, cannot effectively play the work ability. NRF905 wireless transceiver module has the advantages of small volume, high precision, stable operation, strong 36 antiinterference, stable transmission. Especially suitable for frequent smallflow data transfer applications, such as warehouse management, security, data acquisition, environmental monitoring and so on, economy and utility, reducing the cable data transmission on occasion paper is the use of temperature, humidity sensors to collect the temperature and humidity of environment, through wireless transmission, LCD display, to facilitate the people good regulating temperature and humidity. Through the design of data acquisition acquisition of environmental temperature and humidity. After data processing by wireless acquisition module two parameter data is transmitted to a wireless receiving module. Let us know the environment temperature and humidity conditions. In order to achieve the above functions, the main design hardware modules are: microputer minimum system ( STC89C52chip ), an analogtodigital conversion module ( ADC0809) ( DS18B20) module, temperature sensor, humidity sensor modules ( HR31), a wireless transmitting and receiving module ( NRF905), LCD12864 liquid crystal display module, control module and so from the wireless data collection terminal system function design, wireless data receiving end function design software design and development ponents. The first part of the paper briefly introduces the features of STC89C52 MCU and function application。 the second part of this article mainly introduces the performance characteristics of wireless module and debugging application environment, bined with the single chip microputer, wireless acquisition and monitoring system for the overall functional design, which not only defines the system schematic diagram, and the system software function module the third part of the thesis。 according to the wireless acquisition and monitoring system data acquisition receiver function, the microcontroller system circuit schematic diagram design。 the fourth part of the thesis based on the wireless data acquisition system for receiving the function design, to design and software flow diagram, the monitoring terminal using C language programming. Using the software through software simulation, and the use of Ace simulator simulation test was made, intended to plete a thesis. Based on this module, using NRF905 as the wireless transmission module, can develop a variety of extremely optimistic about the prospects of all types of applications, such as: the 37 engine room monitoring, warehouse management, based on the single chip microputer business wireless monitoring system design and development of remote maintenance system. This paper studies how to use wireless module with singlechip microputer system, the wireless service and display control bined, make up for the traditional wired system inadequate, and can be widely used in machine room, library, office, warehouse for environmental control system, convenient and quick. 38 附 錄 附錄 1：整體原理圖 2827262524212223123456783233343536373839VCC40VSS20XAL119XAL218RST9EA/VPP31PSEN29ALE/PROG301011121314151617U1STC89C52VCCP00P01P02P03P04P05P06P07P10P11P12P13P14P15P16P17P20P21P22P23P24P25P26P27P30P31P32P33P34P35P36P37PSENALEXAL130pFC130pFC2GNDK1VCC10uFC310KR1GNDVCCGNDGNDVCCP01P02P03P04P05P06P07P00P35IN0P25P36P27P26P33IN1IN2IN3P34IN31IN42IN53IN64IN75START6EOC7D38OE9CLK10VCC11VREF+12GND13D114D215VREF16D017D418D519D620D721ALE22ADD C23ADD B24ADD A25IN026IN127IN228U2ADC0809GND5KR6VCCP32GND1DQ2VCC3U5ds18b201 2P2R2GNDVCCIN0123456789P6RwP01P02P03P04P05P06P07P00VCC VCC1TX_EN2TRX_CE3PWR_UP4UCLK5CD6AM7DR8MISO9MOSI10SCK11CSN12GND13GND14U3NRF905P31P30P17P16P10P11P12P13P14P15GNDGND123P7 K1GNDVCCD15KR81 2 3P1010uFC1122uFC12GNDGNDVCCGND 圖 22 溫濕度無(wú)線(xiàn)采集模塊 39 D151N4007Q5S8550P21GNDVCCVCC123P5接線(xiàn)端子45123J5GNDD111N4007Q1S8550P25GNDVCCVCC123P1接線(xiàn)端子45123J1GNDD121N4007Q2S8550P24GNDVCCVCC123P2接線(xiàn)端子45123J2GND
