Smart Door Lock System Project

The aim is to control a door lock without keys and using a smartphone to accomplish this. Security and safety are becoming more and more popular day by day and it is getting improved and used for the ease in our life. So in this project we are going to make an iot based door lock system using nodemcu solenoid lock and adafruit io.

There are many kinds of wi fi door lock available in the market which makes your home more secure and saves time in finding the keys.

Smart door lock system project.

Now days technology has become an integrated part of people s lives therefore the security of one s home office or organization must also not be left behind. Here we are also building a similar wi fi door lock which can be controlled from the smartphone. This is a simple project made with the arduino uno r3. Password based door lock system using 8051 microcontroller circuit design uses five major components a microcontroller an l293d motor driver a dc motor a 4 4 matrix keypad and a 16 2 lcd.

Here nodemcu will act as the main controller and connect the user to the door lock system using the internet. The communication medium will be the internet wifi module esp8266. This controller requires a supply voltage of 5v dc. Smart lock door with voice activation using arduino uno project showcase by bangkitwahyu.

This project is to create a smart lock door system with voice activation to open and close the door via voice sensor and arduino uno. Here an at89c52 microcontroller is used and it is an 8 bit controller. I have already posted an tutorial about the same project with bluetooth module you can refer it for any clarifications. Smart receptionist with smart lock system is mainly designed and developed for security system and purposes.
