【正文】 溫濕度采集概述 無線溫濕度采集系統(tǒng)是一種基于射頻技術(shù)的無線 溫濕 度檢測裝置 ，其工作原理： 系統(tǒng)由 發(fā)射板 和接收 板 ，以及顯示芯片 組成。 案列：采用 ZigBee 技術(shù)提出一種無線傳感器系統(tǒng)方案，設(shè)計并實現(xiàn) ZigBee 的無線數(shù)據(jù)傳輸，采用首個符合 ZigBee 標(biāo)準(zhǔn)的 CC2430 射頻芯片作為傳感器節(jié)點(diǎn)的數(shù)據(jù)采集。作為獲取信息最直接、最基礎(chǔ)的方式 ,數(shù)據(jù)采集技術(shù)水平的高低已成為衡量一個國家科學(xué)技術(shù)水平的重要標(biāo)志之一。經(jīng)歷了長度法、干濕法直至今天的電測量的歷程，使?jié)穸葴y量技術(shù)日漸成熟。比如倉庫儲藏的食品，農(nóng)作物的生長 等都會受溫濕度變化的影響；工業(yè)中精密儀器，半導(dǎo)體器材都會因溫濕度值過大 而性能降低。然后通過無線射頻收發(fā)器 SI4432將數(shù)據(jù)發(fā)送到 發(fā)射板 。以往的人工采集數(shù)據(jù)占用人力資源，可靠性低，容易發(fā)生差錯已經(jīng)不適應(yīng)工業(yè)化生產(chǎn)的要求了。 承諾人（簽名）： 年 月 日 杭州電子科技大學(xué)本科畢業(yè)設(shè)計 摘 要 溫濕度的自動測量和顯示記錄是工廠的一項常規(guī)監(jiān)測項目。 發(fā)射板： 溫濕度采集器以 ATMEGA88作為主控制芯片，采用數(shù)字溫濕度傳感器芯片 SHTl0采集外界溫濕度值。 關(guān)鍵詞 ： ATMEGA48； SHT10； SI4432； LCD1602 杭州電子科技大學(xué)本科畢業(yè)設(shè)計 ABSTRACT The automaticmeasure and the records display of temperature and humidity is one of the conventional monitoring projects in the factory. In the past, people collected data themselves. In this way, it needed much human resource with low reliability. Of course error is easy to happen. So this way was not fit to the requirements of industrial production. General temperature and humidity collection system display data monotonous and short of history data. Many of these systems also don?t support the munication with most of PLC. Furthermore, temperature and humidity collection module is difficult to layout as too many lines． It is restricted by the placement of plant also． This paper utilizes ARM microprocessor?ATMEGA48?as the core ofthe platform to buildup system, which is applied widely at board: temperature and humidity logger ATMEGA88 as the main control chip, digital temperature and humidity the sensor chip SHTl0 acquisition outside temperature and humidity valued. Then through the radio frequency transceiver SI4432 data will be sent to launch plate. Receiving plate: ATMEGA88 the wireless RF transceiver as the primary control chip SI4432 received by the temperature and humidity data LCD1602 display, eliminating the a lengthy and laying inconvenience munication cable. The hardware design tasks of the project include: design goals, the host, as well as temperature and humidity acquisition module device selection and schematic design, PCB board design instructions, testing, and debugging.
