基于单片机的气象信息采集系统
摘要:随着科技的发展,气象信息采集技术也得到了快速的发展,从原先的人工定时采集发展到现在的无人实时采集。
气象信息采集是自动采集、处理、传输气象信息的过程。本系统由采集模块、数据传输模块、管理模块和显示模块组成。它采用STC89C51单片机作为管理模块,利用温湿度传感器对室外的气象信息进行实时采集并通过无线传输模块进行无线信息传输。接收端接收到信息后经过处理可直接显示到液晶屏上。通过温湿度设置按键,可以进行警戒温湿度的设定。
关键词:气象信息采集,STC89C51单片机,无线传输模块
Design of Meteorological Information Acquisition System Based on Microcontroller
Abstract:With the development of science and technology, meteorological information acquisition technology also obtained fast development, from the original artificially timing acquisition development up to now unmanned real-time data acquisition.
Meteorological information collection is automatic acquisition, processing and transmission meteorological information process. The system are consists of acquisition module, the data transmission module, management module and display system uses the STC89C51 microcontroller as management module, the outdoor weather information for real-time acquisition is collected by the temperature and humidity sensor DHT11,and through wireless transmission module for wireless information transmission,the information can be received by the receive receiver to receive information after treatment can directly display to LCD the temperature and humidity settings button,you can set the warning temperature and humidity.
Key words:meteorological information collection, STC89C51 microcontroller, wireless transmission module
