The purpose of this project is to monitor and control Power grid devices (Analog and Digital) remotely using smart phone.  The Bluetooth modem provides the communication mechanism between the user and the microcontroller system by means of text messages.   The project aims to design a smart grid monitoring and controlling system through a smartphone. In this project, electrical parameters such as voltage, current, temperature, and frequency are continuously monitored using sensors interfaced with a microcontroller. The measured values are displayed on an LCD and transmitted to the user's Android smartphone through a Bluetooth module. Based on the received parameter values, the user can remotely control the connected electrical devices using an Android Bluetooth application. The microcontroller processes the sensor data and performs the required control operations based on the commands received from the smartphone. The entire system is programmed using Embedded C language. This system helps in real-time monitoring, wireless control, and efficient management of electrical loads.            

The major features of this project are:  

1. Automatic grid parameter monitoring and controlling of power devices.
