Smart Door Lock – Advanced Security with Keyless Entry | IOT Project

Introduction

The Smart Door Lock uses advanced wireless technology to provide secure and convenient access control. The system is powered by a NodeMCU and incorporates a 2-channel relay, solenoid lock, PIR sensor, and battery to control the locking mechanism and provide real-time alerts. The lock can be controlled via a mobile app, allowing users to lock or unlock the door remotely. Additionally, the PIR sensor detects motion near the door and sends an alert to the user’s phone, enhancing security by notifying them of any presence outside.

System Components

• NodeMCU: The main controller for the system, processing commands and controlling the lock and relay.
• PIR Sensor: Detects motion near the door and triggers alerts to the mobile app when someone is present.
• Solenoid Lock: The locking mechanism, which securely locks and unlocks the door.
• 2-Channel Relay: Allows control of the solenoid lock through the NodeMCU.
• Battery: Powers the entire system, ensuring it operates without interruption.
• Mobile App: Interface for remotely controlling the lock and receiving motion alerts.

Working Principle

The Smart Door Lock operates using a PIR sensor and NodeMCU to remotely control the lock and send alerts. When motion is detected at the door, it notifies users for added security.

• Remote Control: The NodeMCU communicates with the mobile app, allowing users to lock or unlock the door remotely.
• Motion Detection: The PIR sensor detects motion near the door and sends an alert to the mobile app, notifying the user of any movement.
• Lock Activation: When the user sends a command to lock or unlock, the 2-channel relay activates the solenoid lock to engage or disengage the lock.
• Alert Notifications: If motion is detected by the PIR sensor, an alert is sent to the user’s mobile device for enhanced security.

Applications

This system has wide-ranging applications, including:

• Home Security: Remote locking and motion alerts for enhanced security.
• Offices and Businesses: Remote access control and security notifications at entrances.
• Apartments: Easy, keyless access for apartment buildings.
• Smart Homes: Integrates with smart home systems for automated access control.
