Password Door Lock System

So in this project we are going to make an iot based door lock system using nodemcu solenoid lock and adafruit io.

Password door lock system.

Traditional lock systems using mechanical lock and key mechanism are being replaced by new advanced techniques of locking system. This allows the user to lock unlock his home s door lock by using a smartphone from anywhere in the world. In this project we will do an automatic door lock system using a 4 4 keypad and servo motor controlled by arduino. Presenting to you the diy password based door lock.

Here nodemcu will act as the main controller and connect the user to the door lock system using the internet. The necessity of a low cost electronic home security system designed in coordination with other security measures is always there in our society to reduce the risk of home intrusion. High security door lock systems can be customized to meet your needs. Password based door locking system design uses five major components a microcontroller an l293d motor driver a dc motor a 4 4 matrix keypad and an lcd.

Here at89c52 microcontroller is used and it is an 8 bit controller. The code for password based door lock security system using arduino keypad is given below. This controller requires a supply voltage of 5v dc. Password protected door locking system.

Keeping this problem in mind we are working on a project on. If password matched then a message password matched access granted is displayed on the lcd and motor rotates and door opened after some time door closed. A simple yet effective means to safeguard your home and office by prev. Password based door lock system using 8051 microcontroller is a simple project where a secure password will act as a door unlocking system.

We type the password using keypad which is attached with the system. The project password detector can be used to automate the door locking process so the user need not to carry the door lock keys along with them they need to just remember the password and use it later to open the door.
