郑州大学毕业设计题 目： 基于 51 单片机的多点温湿度采集和无线传输系统 指导老师： 职称： 专 业： 电子信息工程 院（系）： 信息工程学院 完成时间： 下载后可任意编辑基于 51 单片机的多点温湿度采集和无线传输系统摘要：本系统是基于 51 单片机的多点温湿度采集和无线传输系统，由两个发射模块与一个接收模块组成。发射模块利用数字温湿度传感器 DHT11 采集环境温湿度数据并传送给STC89C52RC 单片机，单片机进行数据处理后利用无线传输模块 NRF24L01 进行无线发送。同时，NRF24L01 具有接收功能，接收模块的 NRF24L01 将接收到的数据传给 STC89C52RC 单片机，最后用数字显示屏 LCD1602 将经过单片机处理后的温湿度数据显示出来。本系统能够完成同时远距离采集两点温湿度并在系统终端进行显示的功能，以达到监测多点环境温湿度的目的。结果表明，本系统能够方便、高效、及时地测量出两个采集点的温湿度。关键词：STC89C52 数据处理 无线传输 温湿度Abstract: This is a multi-point temperature and humidity acquisition and wireless transmission system which is based on 51 single-chip microcomputer .it includes two transmitter modules and a receiver module. Transmission module use DHT11—digital temperature and humidity sensor to collect temperature and humidity data and transmit them to STC89C52RC micro-controller.The micro-controller process the data and use NRF24L01—the wireless transmission module to transmit data wirelessly.At the same time,NRF24L01 have the function of reception. NRF24L01 of the receiver module will transmit the received data to the STC89C52RC micro-controller, and finally use LCD1602—a digital display screen to display temperature and humidity data after the micro-controller process the received data. The system can complete simultaneously and remotely the collection of temperature and humidity and the display of data in terminal features.It achieved the purpose of monitoring multi-point temperature and humidity. The results show that the s...
