摘要
为实现蔬菜大棚温湿度的智能控制,以AT89S52单片机为控制核心,35BYJ46步进电机为控制对象,采用ULN2003A驱动芯片实现对步进电机的转速及定位控制,根据实时采集的温湿度数据,通过控制卷帘门的开度及换气扇的转速,从而调节蔬菜大棚的温湿度。同时,通过M35模块(GPRS)和红外模块可以实现控制系统的远程控制和近程控制。
In order to realize the intelligent control of the temperature and humidity about vegetable greenhouse, AT89S52 single chip microcontroller was taken as the control core to control step motor 35BYJ46, ULN2003A was used to realize speed and positioning control of step motor, according to the real-time acquisition of the temperature and humidity data, through controlling the shutters opening and the speed of ventilator, the temperature and humidity of the vegetable greenhouse was adjusted. At the same time, it could realize remote and short range control through the M35 module (GPRS) and in- frared module.
