ABSTRACT This project is done for monitoring and controlling of three phase induction motor. It is necessary to monitoring the condition of induction motor to get better efficiency and output. Hence, we monitoring the condition of motor such as speed, direction, voltage, current, frequency and temperature. In addition to this we use modern technology which is GSM model(Global Sim Modulation) and Theft Detection technique. For Protection of induction Motor Microcontroller based system is proposed which plays major role than other technique.
