Introduction
It is Automation of the:
• Home
• House work or Household activity.
• It can also use in Offices, Institutes & Industries.
• Home automation may include centralized control:
• Home automation is residential extension of “Building Automation”.
• Lightning of entire house
• HVAC (Heating, Ventilation and air conditioning)
• Appliances and
• Other System (Like Home Weather Station, Digital receptionist, etc.)
Home Automation (HA) provide improved convenience, comfort, energy efficiency & security.

Working Mechanism of Home Automation System
The Working Mechanism of Home automation
System by two ways:
 1)Arduino UNO
 2) Bluetooth Module.
 3) Relay Module
 4) Jumper Wire

Project Description
The project can be better described by dividing it
into two categories, namely,
Hardware:
• Arduino Uno
• Relay Module 1- channel.
• Bluetooth HC-05.
• Jumper wires.
Software:
• Android bluetooth control devices.
• IDE Software (Integrated Development
Environment)

System Data Flow
(Connection Via Bluetooth)
