Embedded Project on Touch Screen Based Home Automation System


The main goal of this project is to develop a home automation system with a touch screen based control panel.

As technology is propelling so houses are additionally getting smarter. Modern houses are step by step shifting from conventional switches to centralized control system, including touch screen switches. Now, conventional wall switches situated in various parts of the house makes it difficult for the client to go close them to operate.

Eventually more it becomes more difficult for the elderly or physically handicapped peoples to do as such. Touch screen panel home automation system furnishes a simpler solution with touchscreen technology. Touch screen control panels are additionally intended for commercial, industrial and medical systems.

In order to achieve this, a touch panel is interfaced to the microcontroller on transmitter side which sends ON/OFF commands to the receiver where loads are associated. By contacting the predefined parcel on the touch screen board, the loads can be turned ON/OFF remotely through wireless technology.

The microcontroller utilized here is of 8051 family. The loads are interfaced to the microcontroller utilizing opto-isolators and triacs.

The further project can be improved by utilizing GSM modem interfaced to the control unit. Utilizing GSM modem, the client can control home appliances by sending a SMS. The advantage of this technology is that there isn’t range limitation when compared to RF technology.
