Remote electrical parameters such as voltage, current and frequency and send these values in real time over the GSM network using the GSM modem / telephone along with the temperature in the power plant. This project is also designed to protect electrical circuits by using an electromagnetic relay. This relay is activated when the electrical parameters exceed the preset values. The relay can be used to operate a switch to disconnect the main power supply. The user can send commands in the form of SMS messages to read the remote electrical parameters. This system can also automatically send the electrical parameters in real time periodically (based on the time setting) in the form of SMS. This system can be designed to send SMS alerts when the Circuit Breaker trips or when the Voltage or Current exceeds the predefined limits. This project makes use of an on-board computer that is commonly referred to as a microcontroller. This on-board computer can communicate efficiently with the different sensors being used. The controller has some internal memory to contain the code. This memory is used to download a set of mounting instructions to the controller. And the operation of the controller depends on these mounting instructions.
