Speed Control Single Phase Induction Motor Using Android Phone

As many of the industries use induction motors. So, controlling of induction motor plays a very vital role. So, our project concentrates on controlling the speed of induction motor using Android phone remotely by the help of the Bluetooth technology. We use Android application which uses Bluetooth to connect to the Bluetooth modem of control circuit which is connected to the motor. Bluetooth modem is interfaced with microcontroller. The Bluetooth slave modem receives the command from the mobile phone. The Bluetooth modem sends the signal to the Microcontroller. The Microcontroller decodes the signal and sends to the relays. Then, respective relay operates to change the speed of Induction motor from 0% to 100%. We are not only controlling the speed of the Induction motor, using feedback network we can also detect the over temperature, high voltage, low voltage, MCB tripping on account of any faults. And we are also adding an extra application which is very important in industries. That is, monitoring of phase lines. Because these types of uncertainties like over temperature, high voltage, low voltage etc are likely to happen in Industries. So, this project will be very helpful in industries, house hold, shopping malls etc.
