Cell Phone Controlled House Automation
I. Introduction
A cell phone is quickly becoming one of the items we never leave home without. Using a cell phone, we wish to be able to control and acquire the status of several devices that exist in one’s home. In particular, we want to be able adjust the temperature using commands sent by a cell phone, and also be able to receive the home temperature status. We would also want to control a security camera remotely for home security purposes.
Benefits:
· Users can receive status of devices in the home while away
· Heating and cooling can be controlled remotely
· Surveillance camera can be switched remotely
Features:
· Ability to use cell phone or an internet connected computer to send commands
· Commands sent through SMS, so nearly any cell phone can be used to send commands
· Bluetooth communication with lights and thermostat, so no extra wiring is needed
· No special software needs to be installed on either the cell phone or computer that sends commands
Performance Requirements
- Indoor transmitter range of at least 70 ft
