IOT Based Automated Gate Unlocking System

Abstract

The gate unlock system using Arduino Uno, servo motor, and ultrasonic sensor is an automated system that enables the unlocking and locking of a gate without any human intervention. This project aims to provide a simple and efficient solution to the problem of gate locking and unlocking. The system uses an Arduino Uno, which is a microcontroller board, to control the operation of the servo motor and ultrasonic sensor. The servo motor is used to control the locking and unlocking of the gate, while the ultrasonic sensor detects the distance of the person or object from the gate. The working principle of the system is as follows: when a person approaches the gate, the ultrasonic sensor detects the distance between the person and the gate. If the person is within the specified range, the servo motor unlocks the gate. The person can then enter or exit, and once they are out of range of the ultrasonic sensor, the servo motor locks the gate again. This project has several advantages over traditional gate unlocking systems. Firstly, it eliminates the need for manual operation, which can be inconvenient and time-consuming. Secondly, it provides enhanced security as the gate can only be unlocked if the person is within the specified range of the ultrasonic sensor. Finally, it can be easily customized and adapted to suit specific needs. The gate unlock system using Arduino Uno, servo motor, and ultrasonic sensor has potential applications in areas such as home automation, security systems, and access control. It can be used in residential and commercial properties, and can be easily installed and maintained by anyone with basic electronics knowledge. Overall, this project is an innovative and cost-effective solution to the problem of gate unlocking and locking.
