花房温度及光照度控制电路的设计

鉴于现在国内科技水平的成果,本着节约成本、控制简单的原则,设计了花房的温度及光照度实时控制电路。利用先进的温度传感器、光照传感器测量温度和光照度,由单片机控制执行单元调节温度和光照度。给出了硬件的设计方案和软件的设计思路。花房温度高、光照度大时后自动放下遮阳网和开启风机,温度低、光照强度小时自动收起遮阳网和开大暖气阀门,使得花房内的温度和光照度控制在设定的范围之内。

Design of Greenhouse Temperature and Light Intensity Control Circuit

In view of domestic results of scientific and technological level at present, based on cost saving and simple control, the greenhouse light and temperature real-time control circuit was designed. The temperature and light were measured by advanced temperature sensor and light sensor, and controlled and run by single-chip microcomputer（SCM）. The design plan of hardware and＇the design view of software were gave. The greenhouse temperature and light were controlled in designed range by putting down the shade net automatically and opening the fan when the temperature was high and the light was large, and folding up the the shade net automatically and opening heating valve when the the temperature was low and the light was small.
