The Design of Intelligent Automatic-Door Based on AT89S52

摘要

With the development of the society, the demand of people's life safety, convenience is higher and higher. In this paper, the system, which is to designed a intelligent automatic induction door, used the microcontroller AT89S52 as the nucleus components, applied the pyroelectric infrared sensor as the detecting sensor, and four phase hybrid stepping motor as drive door. Meanwhile, the HC-SR501 human body induction module is selected in the design, which is composed the German import LHI778 type pyroelectric infrared sensor and dedicated BISS0001 processing chip. Finally, through the connected and download debug hard and soft, the result provides the system is safe and reliable, easy to operate.
