A system and method for measuring, monitoring and controlling electrical power directed through one or more electricity directing devices is provided. The one or more electricity directing devices includes electrical sockets supplying power to one or more devices. The system includes a potential transformer configured to receive AC voltage directed through a socket and further configured to relay the voltage to a processing device. The system further includes a current sensor configured to sense current drawn from the socket and further configured to relay the current to the processing device. A microcontroller is adapted to receive analog or digital values of voltage and current corresponding to AC voltage and AC current. The microcontroller then measures values of voltage and current, calculate electrical power consumed and generate a control signal. The control signal activates a switching device operationally connected to the socket and switches power flow through the socket.

A method for communicating with one or more sensor nodes in a Wireless Sensor Network (WSN) over a network is disclosed. The method includes initiating communication with the sensor nodes by sending messages to the server application using the instant messaging system. The server application formats the received messages and communicates to the sensor nodes and in turn also receives responses from the sensor nodes and communicates them back to the IM client. The method also includes steps for enabling a WSN messaging client to converse with an instant messaging client over the network during communication with the one or more sensor nodes in the WSN. The method further includes identifying the IM client the user has employed for communication and the corresponding IM protocol. Also, the method includes the step of configuring the WSN messaging client with the same IM protocol to enable communication.

An electrical circuit for protecting an electrical load from overload current is provided. The system includes a voltage transformer configured to receive AC mains voltage from an electric mains supply and further configured to apply reduced voltage to the electrical load.
