Design of intelligent control system of greenhouse
Abstract:Most of the greenhouses now has a disadvantage such as consumption of human resources.This article propose a greenhouse auto—control system based on a single chip.The system monitors the environmental factors such as temperature and humidity,then irrigating,heating and cooling automatically in accordance with the requirements of crops.The core control of the system is AT89S52 that collects environmental data by the chip DHT11.The data is displayed by LCD and alarmed by buzzer timely.The design brings the system a great convenience to control the temperature and humidity regularly.The system is simple,high reliability,scalability,and helpful to reduce farmers’labor and increase crop yields.
