大棚温度自动控制系统的设计

摘要
随着大棚技术的普及,温室大棚数量不断增多,对于蔬菜大棚来说,最重要的是一个管理因素是温湿度控制。温湿度太低,蔬菜就会被冻或者停止生长,所以要将温湿度始终控制在适合蔬菜生长的方位湿度控制系统传感器单片机


Abstract
With the popularization of trellis technology, greenhouse trellis an ever-growing number, for vegetable shed speaking, one of the most important management factor is the temperature and humidity control. Temperature is too low, the vegetables will freeze to death or stop growing, so will always control temperature and humidity in a suitable vegetable growth range. Traditional temperature control is in greenhouse trellis internal hanging a thermometer, workers according to regulate the temperature reading the temperature inside the shelter. If only by artificial control both consumption manpower , and easy to place regular orders. Now, with the improvement of agricultural industry scale, for larger quantity of trellis,tradition temperature control measures will show great bureau sex. Therefore, in modern vegetable shed management zhongtong often temperature and humidity automatic control system, in order to control the temperature the temperature, adapt to the trellis vegetable production needs.
This thesis mainly elaborated based on AT89C51 tomatoes canopy temperature and humidity control system design principle, main circuit design and software design, etc. This system USES AT89C51 single chip puter as controller, SHT10 as controller, SHT
