A remote telephone-controlled home automation system

We present a home automation system using telephone lines. The system consists of two subsystems. One is the remote control system. The other one is the phone monitoring system. The remote control system used the dual tone multi-frequency signals to control the operations of various appliances. The hardware and software are designed based on the standard telephone system. The phone monitoring system provides convenient services for the user to better monitor the usage of their phones. Experimental results show that the two subsystems provide better home services and living quality for modern lives.
