Smart Fingerprint-Based Door Lock System with GSM Alert Using Raspberry Pi Pico
Objective
To design and implement a secure door access system using Raspberry Pi Pico and fingerprint authentication, ensuring only authorized users can unlock the door. Additionally, to enhance security by integrating a GSM module that sends real-time SMS alerts during unauthorized access attempts.
Abstract
The Smart Fingerprint-Based Door Lock System with GSM Alert Using Raspberry Pi Pico is a secure and cost-effective solution designed for enhanced access control in homes and offices. It uses a Raspberry Pi Pico microcontroller to interface with an R307 fingerprint sensor that identifies and verifies authorized users through biometric authentication. When a valid fingerprint is detected, the system activates a relay module to drive a DC motor, which opens the door. In case of an unauthorized access attempt, a SIM800C GSM module sends an SMS alert to the registered mobile number, notifying the user of the security breach. This integration of fingerprint-based access with GSM alerting offers a reliable and real-time security mechanism, eliminating the risks associated with traditional locks and password-based systems.
