Abstract

PURPOSE: An automatic door for a refrigerator using the infrared sensor is provided that it prevents from the food being damaged, the power consumption is reduced. CONSTITUTION: An automatic door for a refrigerator using the infrared sensor comprises a motor. By using the motor when the refrigerator door is held, the refrigerator door is closed automatically. The consulting switching state of refrigerator is sensed by using the infrared sensor. The switching time of the refrigerator door is adjusted by using timer. The closure of the refrigerator door is informed to speaker to the user.

Description

Refrigerator automatic door using infrared sensor {Autodoor using infrared sensor}

Refrigerator automatic opening and closing door using electronic circuit

Currently, the refrigerator only serves to store food.

I tried to configure it because the door may not be closed properly by mistake, and the person who is forgetful may just open the door and not close it again.

It is designed to automatically open and close the door of the refrigerator using an infrared sensor.

You can prevent food from spoiling. The power consumption can be reduced by preventing the door from being kept open.

1 is a circuit diagram of a design.

The regulator with a voltage of 12V outputs a constant voltage of 5v. This voltage enters the infrared sensor, and the infrared sensor detects a person or object and acts like an on / off switch. This voltage goes to 555timer, and it is possible to adjust the time through preset resistor or variable resistor so that the time until the door is closed is about 5 seconds as the delay time and the voltage transmitted through the relay switch is about 5 Allow the motor and speaker to spin for a few seconds to let the owner know by sound that the door is closed.

Claims (3)

Using a motor to automatically close the door when the refrigerator door is open. How to determine if the door of the refrigerator is open using an infrared sensor. How to adjust the opening and closing time of the refrigerator using 555timer.
