A study paper on power management in electrical devices using Zigbee network This paper deals with the study of the control mechanism and the practical application of electrical appliances using an android phone in a Zigbee network. The system measures the voltage and current parameters of electric devices and thus helps to view the power consumed. The proposed system is a flexible system which provides an efficient and effective control mechanism from a remote location. The system also focuses on voice based control and thus helps to save the electricity expense of the consumers. The other alternatives to Zigbee are also discussed in the paper.
