Abstract:
Today every thing is going to be digital and wireless, and the cell phone is the key player in wireless technology, the trends in wireless technology changing day-by-day and today the work is going on how to develop remote devices. Remote communication allows us to control electronic devices without having to be near them.
The objective of this project was to design asystem to be controlling (switch on or off) electronic devices remotely via GSM network without the presence of man and to reduce the time factor.
There are two key components to the project design,
1-Remote unit
This unit consists of cell phone which is present in the remote place.
2-Local unit
This contains one cell phone and a Local Control Section, Local Control Section consists of a DTMF Receiver (DTMF decoder), BASIC Stamp 2-IC, ULN2003 Darlington Driver and the electronic devices
The remote unit (mobile) remotely controlled (turned off /on) the electronic device successfully
