Bluetooth is the buzz word, while designing any automation system for study purpose. Automation of Home/Work place is common using short range communication technology, called Bluetooth. This is because it is hard to keep good communication between line-man/Maintenance staff and the Electric Sub-station Staff, where Sub-station is usually placed at distant place. The Bluetooth enabled Android Mobile Phone can be used as password entry device and control the Main-power line cut-off process by standing at safe and comfortable place.
