本设计用18D02温度传感器在探测端采集周围环境的温度数据，经过单片机处理，由NRF24L01无线模块发射传输至监测端，实时显示到液晶屏上。同时，在监测端连接一个蜂鸣器，当俩无线模块连接出现问题时，蜂鸣器提示报警。这样确保了对环境的实时监测。

摘要

在科技飞速发展的今天，环境监测已经逐渐向现代化、自动化、科技化、科学化等发展，在农业、工作环境方面就显得尤为重要，特别是环境监测方面，怎样才能提高作物的产量、怎样的环境才是作物适应的，作物生长需要的什么样的温度、湿度，需要的光照度是多少；怎样才能在危险的区域施工而不用担心事故发生和减少因为外界环境变化而引起的事故。这些信息我们怎样来获得，这就需要我们用科学的力量来解决这个问题，也正因如此，本课题就应运而生了。

本系统采用单片机为主控制器。设计的主要思路是通过传感器监测环境温度、湿度的变化和光照的有无，并将采集的数据传输给单片机AT89S52进行初步处理，再通过带有自定义无线传输协议的电路传送给控制终端，并在控制终端上显示采集到的环境信息。

本课题主要由AT89S52单片机和NRF24L01无线传输模块制作一个监测探测，基于DS18B20、HS1101传感器及光敏电阻的温湿度和光强的自动检测系统，监测探测可以分别于各探测节点直接监测，并能传输当前探测到的环境温度、湿度和光照信息给终端节点，配合终端硬件设计完成整个终端部分的软件设计，目的是利用毕业设计的这段时间学习一种利用AT89S52型单片机对环境进行控制的方法。

Abstract

In technology rapid development today, environment monitoring has gradually to modernization and automation, technology and scientific development, such as in agriculture, working environment is particularly important, especially environment monitoring, how to increase crop yield, how to adapt to the environment is the crop, crop growth need what kind of temperature, humidity, need what is the light; How to in dangerous area construction and don't worry accidents and less because of external environment change and cause accidents. The information we can get, this needs we use the power of science to solve this problem, also because of this, this topic is made.

This system mainly adopts single-chip microcomputer controller. Design of the main ideas is through the sensor to monitor the environment temperature, humidity changes and illumination, and will have collected data transmission give monolithic integrated circuit AT89S52 preliminary treatment and then through wireless transmission agreement with custom send control circuits, and in control terminals terminal display on environmental information collected.

This thesis mainly by NRF24L01 AT89S52 SCM and wireless transmission module making a monitoring based on DS18B20, HS1101 detection, the temperature and humidity sensor and photoconductive resistance of light intensity, automatic test system for the difference in the monitoring detection can detect nodes directly, monitor, and detects to transmit the current environmental temperature, humidity and light information to the terminal node, with terminal hardware design to complete the whole terminal part of the software design, the purpose is to use of graduation design this time learning a use of AT89S52 SCM control type of environment method.
