Design of Automatic Sensor Door System Based on Microcontroller
With the continuous growth and development of social economy,people's material requirements and living standards gradually improve the requirements of the traditional sliding door has slowly faded out of people's vision,followed by the gradual adaptation of the intelligent automatic door.In supermarkets,hotels,banks and other types of modern buildings in the automatic door is essential,automatic door has also become an important measure of the degree of intelligence of the building one of the measurement indicators.This design is based on the microcontroller automatic sensor door control system,to the microcontroller as the core,the choice of pyroelectric infrared spectral sensor to detect whether there is a person to enter,it can effectively detect the human body infrared spectral changes in the situation,and produce different analog signals to command the LCD display information as well as stepping motor control of the door open and close.
