基于Arduino的温湿度系统设计
摘要:在我们现在的生活当中，温度与湿度的监测技术很重要的被利用于特殊的环境、环境温度湿度要求比较苛刻的区域，其使用的范围还是比较宽广，使用频率也很频繁。
生活发展到今天，测量和系统控制方面要达到目的，必须需要使用传感器，它是测量和系统控制类的重要组成部分。我们都了解那些起始被测信号，如果不使用测量仪器对其进行精准的捕捉及进行模拟转数字信号，那么我们所期望的智能监测类系统将无法工作，而这方面问题的解决传感器表现出巨大的优越性。假如在仓库管理系统中增填温湿度智能监测系统，那么对于管理人员来说，相比传统的非智能状况，相关人员的工作量会适量减少，对于温室种植业的实践生产经验表明，提高温室环境的管理水平和自动化控制水平可以有效发挥温室作物生产的高效性。
本系统是一个基于Arduino的温湿度控制系统，Arduino UNO是整个系统的核心，其就像电脑的CPU一样，处理传感器输入输出信号；该系统通过一DHT11温湿度传感器来采集环境中的温湿度数据，DHT11数字温湿度传感器是一种含有已校准精度的数字信号的输出温湿度多用途传感器。它采用的专用数字模块采集技和温湿度传感技术 ，具有非常高的可靠性与优越的长时间使用稳定性，再通过LCD1602液晶显示器进行观测。当环境中的温度数据达到临界值时通过蜂鸣器蜂鸣进行报警，湿度达到极限值时LED灯发光报警。
本课题的研究解决了人们生活环境中温湿度测量的易读性，减小了由于人类肉眼观察温度计带来的误差。同时可以应用于一些农业对于温度要求比较高的场所，设定温度界限，达到温度极限及时提醒人们采取措施，保护农作物不受环境伤害，减小损失。也可以增添通信模块，把温度信息实时反馈给用户，来实现“足不出户“就可以对农作物场所温度进行了解。极大的为人们提供方便性，可靠性。比起传统的温湿度计，有了非常大的实用意义和运用价值。

Design of temperature and humidity system based on Arduino
Abstract: In the life we are living now, temperature and humidity monitoring technology is very important is utilized in special environment, environmental temperature and humidity requirements more demanding areas, the scope of its use is quite broad, frequency of use is also very frequent.
Life development today, the measurement and control system to achieve the goal, must require the use of sensor measurement and control system, it is an important part of the class. We all know the starting signal to be measured, if you don't use measuring instruments on the to accurately capture and simulate digital signal, so we expect the intelligent monitoring system will not work, and the problem of solving the sensor performance out great superiority. If the warehouse management system, increased fill temperature and humidity intelligent monitoring system, then for management personnel, compared to traditional non intelligence, his workload will be appropriate to reduce, for greenhouse planting production practices show that improving the management level of the greenhouse environment and automatic control level can play an effective role in the efficiency of greenhouse crop production.
The system is of a control system based on the temperature and humidity of the Arduino, Arduino uno is the core of the whole system, its just like the computer's CPU, input and output sensor signal processing; the system through DHT11 temperature and humidity sensors to collect environmental temperature and humidity data, DHT11 digital temperature and humidity sensor is a containing the calibration accuracy of the digital signal output temperature and humidity multipurpose sensor. It uses the special digital acquisition module technology and humidity sensor technology has very high reliability and excellent long time stability, and through the observation of LCD1602 liquid crystal display. When the temperature and humidity data in the environment reaches a critical value through the buzzer alarm.
Research on this subject solves the legibility of measurement of temperature and humidity in people's living environment, reduce the human eye observation thermometer error. At the same time can be used in agriculture for the temperature requirements for high places, to set the temperature limit, to remind people to take measures to limit temperature, protect crops against environmental damage, reduce losses. Can also add communication module, the temperature real-time feedback of information to the user, to achieve "home" can be to understand the place of crop temperature. Great for people to provide convenience, reliability. Compared to the traditional temperature and humidity, there is a very large practical significance and application value.
