We reside within the world of automation wherever most of the systems have gotten machine-driven, like industrial automation, homes and alternative business sectors. Home automation is employed to manage and monitor electronic security systems, appliances, audio or TV equipment. It is the residential extension of a building automation and its an automation of the house, housekeeping or home activity. The advantages of home automation are that its saves time, money, maintenance prices and secure, makes life easier. The home automation devices include PLC, Insteon, X10, UPB, Crestron, Z-Wave, Lurton-RA.It is possible to develop home automation android using different technologies like GSM Module, Arduino, WiFi, Zigbee and different controllers like SCADA, PLC.
Home Automation System
Home automation system makes the operations of assorted home appliances a lot of convenient and saves energy. With the energy saving conception, home automation or building automation makes life terribly straightforward today. It involves automatic dominant of all electrical or electronic devices in homes or perhaps remotely through wireless communication. Centralized management of lighting equipments, air con and heating, audio/video systems, security systems, room appliances and every one alternative equipments employed in home systems is feasible with this technique.
Home automation systems are classified into the following three types depending upon the type of controllers such as
- Wired or Bus Cable Home Automation
- Power Line Based Home Automation
- Wireless Home Automation
The Structure of Home Automation System
Home automation system is especially enforced by sensors, dominant devices and actuators as shown within the figure. The sensors detects lightweight, motion, temperature and alternative sensing parts, and then send that information to the most dominant devices. These sensors are often thermocouples or thermistors, photograph detectors, level sensors, pressure sensors, current transformers, IR sensors, etc., which require an extra signal conditioning instrumentation to connect with the most controller.
Controllers could also be personal computers or laptops, touch pads, good phones, etc., connected to the dominant devices like PLC’s that receive the data from the sensors, and supported the program.This program is often changed supported the load operations. The programmable controller permits to attach varied sensors and actuators through varied input and output modules whether or not they are a unit analog or digital.
Actuators are ultimate dominant devices like limit switches, relays, motors and alternative dominant mechanisms that finally control the house equipments. Communication system plays an essential role during this home automation system for the remote access of those operations. This good home system additionally provides continuous observance through video surveillance with cameras, scheduling, and energy saving operations. This can be the most effective solution even for the senior and the disabled persons to control equipments.
Android Home Automation
Generally, in present modern world peoples are addicted to using modern equipment.The main goal of this project is to control each and every appliance of industries or household using Android OS based smart phone or tablet. There are various android applications available in the market to turn our android OS based gadgets into a remote control to control a system in our home or to get started, we need an INSTEON controller and controllable devices.Some of these android applications are MobiLinc, conductor, Touch Switch etc.
For a better understanding of this home automation using android concept, this project for home automation with Android application is handy:
- 8051 series microcontroller
- Opto Isolator
- Voltage Regulator
- Bluetooth Device
- Push button
- Android Application
- Embedded C or Assembly language
- Keil Software
Power supply comprises of four stages, mainly: transformer, rectification, smoothing and regulation. In the first stage,transformer steps down the voltage, in the second stage, a bridge rectifier converts an AC current to DC current. In the third stage, AC ripples are removed with the help of a capacitor. In the final stage, regulator regulates the power supply as per the requirement of the circuit.
In present days, houses are becoming smarter by step by step shifting from typical to centralized switches. These switches are placed in various places in the house These switches are difficult to operate for the users, particularly for physically handicapped people as they’re difficult for them to approach and operate. The android home automation system provides a easy solution to home automation.
In this android home automation project, a 8051 microcontroller is employed from the 8051 family and therefore the loads are interfaced with the microcontroller by using Opto Isolators and TRIACs. The remote operation is done by android smart phone with a GUI (graphical user interfaced) based touch screen operation.GUI is a type of user interface, that permits users to interact with the electronic devices through graphical icons. These are often found in mp3 players, diversion devices, trade instrumentality and household appliances.So,as to realize this, android based smartphone acts as a transmitter and sends ON/OFF commands to the receiver wherever loads are connected. Therefore, by using wireless technology, we will operate the remote turn on the transmitter and the loads often turn ON/OFF remotely.
