IDEA

Hello dear. For home automation, you can on/off all the room appliances with speech commands. That will be more helpful for elder people or luxury for you. Also you may add some speech dependent voice recognition chip which will let you on appliances by recognizing your speech but will not work for others, so a type of security for room appliances or electrical operated cupboards etc.

The room can also have certain mood sensors or a system to set the temperature and lights of the room according to the mood of person entering it and the weather outside.

I have worked on prototype which uses GSM module to accept commands via sms text, Voice recognition module for speech dependent commands, touch screen for menus, keypad, info. All modules communicate via serial ports. Atmega 328P was more than enough. You can use I2C port with MCP23017 chip (upto 8 chip can br used) for port expansion (8x16) ports.

With this and software serials, you can have a head module communicate with upto 5 serial port modules and 128 switches. One serial module can be another Atmega 328P which can handle other expensive tasks (multi core architecture)

I can help you with prototype and coding.

Happy Automation
