Abstract

With the sensor technology changes with each passing day,the intelligence of product features become more mature,and automation is the key to improving resource utilization.

With the rapid development of electronic technology, microelectronic technology has been applied more and more, at the same time affected our lives in all aspects of the work.Automatic window control system has experienced from scratch, and gradually the development of rich functionality and reliability.This paper will describe is a kind of according to the infrared remote control to the automatic window control system principle and process.

Single chip for its high reliability, cost-effective, low voltage, low power consumption and a series of advantages, has been the rapid development and promotion of large-scale, widely used in various areas of the.The design is based on single chip as the core, combined with other devices, circuit design to realize the shutter control.

The paper introduced one kind based on the STC89C52 single-chip infrared remote control stepper motor design, the system is divided into infrared remote control coding and decoding, LCD display and drive a stepper motor three modules, design of the system can be controlled by a remote control stepper motor, and the stepper motor state through the LCD module of real-time display, enable people to directly see the stepping motor running state.The report on the work principle of the

system, the hardware circuit and software are introduced in detail.

The intelligent irrigation system has energy-saving,high efficiency and low cost.the system has great practical space in different place.

The system has strong practicability, simple operation, strong expansibility.

Key words:Micro controller; Humidity sensor; Temperature sensor; The real time controls
