毕业设计(论文)题目：无线温度湿度采集系统的设计院系：专业：班级：姓名：学号：指导教师：II无线温度湿度采集系统的设计【摘要】随着工业农业等相关产业的不断发展，温度和湿度的测量在实际生活中的应用越来越广泛。如现代温室大棚，酿造酒类，微生物发酵，药物制造等方面均对温度湿度的要求严格。本设计为一个无线温湿度采集系统。以STC89S52为主要芯片，利用数字式温湿度传感器DHT11采集温湿度，把收集到的数据传给单片机STC89S52，再用无线发射模块Nrf24l01将经过处理的数据发射出去。单片机通过模拟SPI口跟NRF24L01之间传送数据。同时，NRF24L01具有接收功能，接收模块的NRF24L01将接收到的数据传给STC89S52，最后用数字显示屏LCD1602将经过单片机处理后的数据显示出来。【关键词】STC89S52数据处理温度湿度IDesignofwirelesstemperaturehumidityacquisitionsystem【Abstract】Withthecontinuousdevelopmentofindustryandagricultureandrelatedindustries,thetemperatureandhumiditymeasurementusedmoreandmorewidelyinthepracticallife.Suchasmoderngreenhouses,brewingwine,microbialfermentation,soondrugsmanufactureoftemperaturehumidityrequirementsstrictly.Therefore,todesignawirelesstemperatureandhumidityacquisitionsystem.STC89S52asthemainchip,usingdigitaltemperatureandhumiditysensorDHT11tocollecttemperatureandhumidity.PassthecollecteddatatoMCUSTC89S52,reoccupyNRF24L01wirelesstransmittingmoduledatawillbeprocessed.SinglechipmicrocomputersimulationSPImouthtotransmitdatabetweenNRF24L01,meanwhile,hasthefunctionofreceiving,receivingmodulesNRF24L01willreceivesthedatatoSTC89S52devices,withdigitaldisplayLCD1602willfinallyafterdealingwiththesinglechipmicrocomputerofdatadisplayed.【Keyword】STC89S52dataprocessingTemperaturehumidityIIIII目录1绪论.................................................................11.1引言...............................................................11.2选题背景及意义.....................................................11.3国内外现状及发展趋势...............................................11.4研究内容...........................................................22系统总体设计方案.....................................................32.1温湿度传感器的选择.................................................32.2无线发射模块的元器件选择...........................................32.2.2NRF24L01的工作模式...............................................42.3单片机的选择.......................................................52.4显示模块的选择......................................................63硬件电路设计.........................................................73.1温湿度采集模块的设计...............................................83.2无线发射接收模块设计...............................................93.2.1温湿度数据的控制发送.............................................93.2.2温湿度数据的接收................................................103.2.3模拟SPI口的实现................................................103.3LCD1602液晶显示模块设计...........................................113.4电源模块设计......................................................124软件设计............................................................124.1采集模块软件设计..................................................124.2发送接收模块软件设计..............................................134.3显示模块软件设计...................................................174.4调试..............................................................17结论..........................................
