基于单片机的小型气象台系统设计

Design of small weather station system based on single chip microcomputer

文章针对各种环境问题对人们产生的不利影响,为了方便人们提前做好预防措施,设计了小型气象台系统。设计以单片机STC89C52为控制中心,运用相应的传感器完成对环境中温度、湿度、风速以及PM_(2.5)的数值采集,对模拟量进行A/D转换之后,通过无线传输模块传送数据,最后在LCD1602液晶显示屏完成数据显示。测试结果表明温度在-20℃~+60℃之间,湿度的数据在0.0%~99.99%之内,在有烟雾等细小颗粒存在的状况下,PM_(2.5)的值较大。

In view of the adverse effects of various environmental problems on people,it is convenient for people to take measures in advance,and a small weather station system is designed.The design takes the single chip STC89C52 as the control center,and uses the corresponding sensors to complete the numerical acquisition of temperature,humidity,wind speed and PM_(2.5) in the environment.After A/D conversion of the analog quantity,the data is transmitted through the wireless transmission module,and finally the LCD1602 liquid crystal.The test results show that the temperature is between-20℃~+60℃,and the humidity data is within 0.0%~99.99%.In the presence of fine particles such as smoke,the value of PM_(2.5) is larger.
