基于AT89C51单片机的红外线自动感应门设计

As technology continues to advance, automatic doors have become increasingly popular in people's daily lives, with higher demands for safety and performance. The control system of automatic doors is a high-tech product that has emerged with people's pursuit of better living conditions and the continuous development of technology. Due to the strong adaptability and high stability of single-chip systems, this design uses the AT89C51 single-chip microcontroller as the main controller. This design focuses on an infrared automatic door control system, using an infrared sensor as the detector to convert the infrared energy changes emitted by the human body into electrical signals and transmit them to the single-chip microcontroller. An AC motor is used as the door driving device, with the single-chip microcontroller controlling the AC motor to automatically open the door when a person approaches, and close the door when the person has entered. The main goal of this project is to realize infrared detection and a single-chip microcontroller control system based on the AT89C51. In conclusion, this design showcases the integration of infrared detection technology and single-chip microcontroller control to create an efficient and reliable automatic door system. Through the use of advanced technology and precise control mechanisms, this system not only enhances convenience and security for users but also demonstrates the endless possibilities for technological innovation in our daily lives.
