Abstract
In this high-tech world, there are hundreds of mechanical machines and electronic products being introduced in market, on weekly basis, to increase the comfort level of human beings. However, to operate on these devices, more power is required. More power generation means more energy requirement and so energy resources. However, today world is facing critical energy resource shortage and "Green House Effect" problems. There are bunch of research projects going on to reduce the total power consumption and at the same time maximize energy/power efficiency. So this project is done as an effort to address the above issue- maximizing the power efficiency and minimizing the power usage. Aim of this project is to control and monitor the power usage of the devices with the help of low-cost, low-power technology known as Zigbee Technology.This project also focuses on developing a Graphical User Interface through which one can control and monitor the power usage of different devices. The graphical user interface give commands to embedded board using Zigbee wireless technology, which in turn controls the switching ON or OFF of different devices. Overall project can be divided into two modules Power Measurement Embedded module and Home server Module. Power Measurement Embedded Module contains power measurement circuit, Microprocessor Control Unit and Zigbee Transceiver. On the other hand, Home Server Module contains Zigbee Transceiver and module through which one can send commands. This project focuses on the Home Server module in which one can send commands to control the devices as well monitor the power consumed by the devices. This project also includes a webpage development through which one can monitor and compare the power consumed by the devices in a tabular form as well as in a chart. This user-friendly representation of the data allows user to understand the power consumption by the devices easily and effectively.
