This project is developed for speed monitoring and control of induction motor through Internet.

It consists of a microcontroller unit. The embedded controller is the CPU that decides the operation of the unit. The embedded controller used here is PIC16F73 microcontroller. Since the controller has the inbuilt peripherals it is called as embedded controller.

An opto coupler with IR transducer is connected with the induction motor to sense the speed of the motor. According to the speed of the motor, the sensor sends signal to the microcontroller.

The microcontroller sends corresponding signal to the PC through serial port. The software in the PC is developed for receiving the data and displaying the speed.

The user can view the speed and also control the speed of the motor in online manner.

When the user presses the specific button in the PC, the software sends corresponding signal through the Internet. The microcontroller receives the signal through USART and controls the operation of the motor.

The microcontroller program is written in assembly language and the Design and port programs are written in ASP.Net.
