PAGE  PAGE III 毕业设计（论文）中文摘要 环境监测在日常生活、工作和工程实践中具有重要的应用。随着生活水平的提高和科学技术的进步，无论是工业还是农业或者是日常生活中对环境监测，特别是恶劣工业环境的监测要求越来越高。不仅要做到低耗，还要求进行一定距离的传输。基于这点我们运用两片主控芯片，传感器，解决了这个日常生活工作中的问题。出于成本考虑我们采用了C8051F单片机和NRF24L01无线收发模块为核心器件，同时附加多种传感器采集数据，系统实现了对环境中温度、氧气、有毒气体浓度等参数的实时监测，从而打破传统温度操作受到距离限制的缺陷。在经过软硬件测试后，我们基本实现了用温度传感器采集温度，用NRF24L01进行一定距离传输后在接受端的电脑上显示出来。因此，该系统是一种低成本、体积小、可移动、方便操作的新型环境监测仪。 关键词：C8051F NRF24L01 温度 无线传输  PAGE  毕业设计（论文）英文摘要 Title： NRF wireless module based on environmental monitoring system Abstract： Environmental monitoring in daily life, work and engineering practice has important applications. With the improvement of living standards and scientific and technological progress, whether industrial or agricultural or environmental monitoring in daily life, especially in harsh industrial environments monitoring increasingly demanding. Not only to be low, but also requires a certain distance transmission. For this we use two main chips, sensors, solves this problem in daily life and work. For cost reasons we have adopted a C8051F340M microcontroller and NRF24L01 wireless transceiver module as the core device, and a variety of sensors collect additional data, the system implemented in the environment temperature, oxygen, toxic gas concentration and other parameters of the real-time monitoring, thus breaking the traditional temperature operation subject to distance limitations defects. After the hardware and software testing, we basically achieved using temperature sensors collect temperature, a certain distance with the NRF24L01 after transmission on the receiving end of the computer display. Therefore, the system is a low cost, small size, portable, easy to operate a new type of environmental monitoring instruments.
