This Project presented a method to control speed of induction motor using mobile phone and DTMF decoder. From the convenience of a simple cell phone, a user is able to control and monitor virtually any electrical device. This will be essential because of the wide range of technical knowledge that homeowners have. The popularity and availability of the mobile and mobile network makes this kind of control very useful and powerful. The main advantages of the proposed system are its reliability, low cost, and wide area coverage.
