摘要
本文介绍了基于AT89C55WD单片机设计的温室测控系统。该系统能完成温室内的温度、湿度、光照及CO_2等参量的采集。配合外围功能部件,实现对上述参数的控制。同时,可与上位机进行RS-232串行通信,并能将温室内的环境参数的详细历史资料存储在EEPROM中备查。
This paper introduces a measurement and control system of greenhouse based on the AT89C55WD.The system can realize some parameters collection such as the temperature,the humidity,the illumination and the CO2 Concentration.Working with its function part,the system can change above-mentioned parameters. At the same time,it can transmit the detected data into PC by means of RS-232 protocol ,and record these historical data into the EEPROM.
