摘要
光、温度、湿度是农业生产不可缺少的因素,但目前市场上的温度检测仪器大都是单点测量,而且温度信息传递不及时,精度达不到要求,不利于农业控制者根据温度变化及时作出决定。而湿度传感器价格昂贵,大多使用进口元件,但事实上,现在国产湿度传感器完全可以使用。为此,本文设计了一种AT89C51单片机为核心,能够综合处理多点温度信息,并能进行光控和湿度控制的温室测控系统。该系统实时性高、精度高、成本低,具有广泛的实用性。
Light,temperature,humidity are the indispensable factors of agricultural production,but currently on the market temperature detection instruments are mostly single-point measurement,and the temperature information is not seasonable and can＇t,reach the required precision agriculture controllers.And it is not helpful to make decisions according to temperature changes timely.And humidity sensors are expensive,the most using imported components.But in fact,now domestic humidity sensors can apply.Therefore,this paper introduces a design with AT89C51,which is handle comprehensive information,and can perform temperature and humidity control of electric control system of greenhouse.The system is high performance,high precision,low cost,with a broad range of practicability.
