Infrared sensors using the automatic opening and closing of the home front door

摘要

The present invention relates to an automatic opening/closing home front door using an infrared sensor. When a user approaches the front door while holding a card key, the present invention is interlocked with an infrared sensor to detect motion with infrared light, and when the door is opened, a handle is directly handled by an automatic opening/closing device. By allowing it to be opened automatically without holding and turning it, it solves the problem that it is difficult to open the handle directly when holding a luggage or child, thereby solving the problem that it is difficult to open the handle directly when holding a luggage or child. That is, the present invention has a rectangular shape to be closed and opened in a home front door, a style made of iron, a handle made of an alloy material, a handle made of an alloy material in the form of a'a' shape to open and close the door by holding and turning it by the user. An automatic opening/closing device equipped with an automatic opening/closing sensor in the style so that it can be opened automatically without holding and turning.When a user approaches the front door while holding a card key, it is interlocked with the infrared sensor to detect motion with infrared rays so that the door can be opened. It is composed of an infrared sensor linked to a card key that has an infrared sensor linked to the card key in the style. Therefore, the present invention is linked with an infrared sensor to detect motion with infrared rays when the user approaches the front door while holding the card key, so that when the door is opened, the door can be opened automatically without holding and turning the handle directly. By solving the problem that it is difficult to open the handle directly when holding a luggage or child, it has the effect of solving the problem that it is difficult to directly open the handle when holding a luggage or child.
