Smart Home project

A GUI-based smart home that enables the user to monitor and control his home remotely using a web application and only one microcontroller (ATmega32).

Features

1- Web-Application Features

a) User can monitor indoor temperature

b) User can monitor and control Door lock

c) User can monitor and control Fan status

d) User can change Door lock password

e) User can change light intensity of the home

f) User can control his electrical devices

g) User can see the current weather status

h) User can use voice commands to control the house (as a form of smart assistance)

2- Embedded System Features

a) Communication is wirelessly using HC-12 (Half-Duplex Wireless 433.4-473.0 MHz RF module)

b) User can enter the door lock password using a keypad

c) User can interact using LCD 2*16

d) Fan can be manually controlled or automatically controlled using the indoor temperature of the LM35 sensor. Speed is set using the PWM of the timer

e) Light can be manually controlled or automatically controlled using the indoor light intensity of the LDR

f) Electrical devices control is done by using a relay, which are controlled remotely from the application.

g) Password is saved on the internal EEPROM of the microcontroller

h) Door can be locked/unlocked remotely using servo motor (simulating door lock)
