Touch Screen Based Home Automation System

Touch screen based is a system that Controls automatically such as fans, fridge, lights and all type of other appliances which are mostly used in homes. With the passage of time, the world is becoming advance more and more as well as our daily used items are also becoming smart and smart. Similarly, home appliances are also becoming smart and smart therefor it is so much necessary that their control should be also smart means their control should be automatically. Currently, in our homes we have been using wall switches for controlling the home appliances which are installed at different walls of our homes. Sometimes, it is very difficult for the user to operate these switches specially for the elder and physical handicapped user.

So many systems are available in market which have been using for controlling the home appliances automatically, but they are not so much efficient and reliable as well as their cost is also so much high. Beside this these systems are also do not have touch screen facility for controlling the home appliances. On concentrating the above issues here, we have designed a device that is called a touch screen based home automation system. This system has designed with the help of touch screen LCD, ac transformer, bridge rectifier, voltage regulator, RF transmitter, encoder and microcontroller 18F452 belongs to pic family. This system is more efficient, more reliable and less costly as compared to other systems.

Here is the block diagram of touch screen based home automation system with all their essential components,

 

Working of Touch Screen Based Home Automation System

This touch screen based home automation system turned no or off the home appliances automatically when is directly connected with 220V ac supply. When is connected with 220V ac supply then single-phase ac transformer steps down 220V ac into 6 or 9V ac. Because this touch screen based home automation system mostly consists of electronics components therefore these ac voltages are converted into dc with the help of bridge rectifier. Then these dc voltages are regulated into 5V dc with the help of voltage regulator. LM 8705 voltage regulator have been used here. Microcontroller and RF transmitter are operated at 5V dc therefore these are powered up with this voltage regulator. Similarly, the touch screen LCD panel operated at 3V dc therefore it is powered up with separate 3V voltage regulator and here LM 7803 voltage regulator have been used for this purpose.

 

Applications and Advantages Touch Screen Based Home Automation System

  1. This touch screen based home automation system could be installed in domestic and industrial building for controlling their loads automatically.
  2. This system could be installed in that remote areas where conventional switches are permitted to use such as highly inflammable areas.
  3. This system is less costly, more efficient and more reliable as compared to other home automation systems.
