This thesis examines the design, construction and implementation of a microcontroller-based long range wireless power monitoring system, suitable for both domestic and industrial use. At its core, the system is based on a number of PICAXE 20X2 microcontrollers and a pair of XBee Pro wireless modules, which are capable of wireless communication to distances exceeding 1.5km.

The Long Range Wireless Power Monitoring system is capable of galvanically isolated single and three-phase current and voltage measurements and is able to calculate real power, apparent power and power factor. The results can be displayed numerically or graphically on a Graphical Liquid Crystal Display. In addition to this, the system has the ability to log usage to an external USB Flash device, allowing for later analysis and for the building of a usage history library.

The Long Range Wireless Power Monitor is equally proficient at measuring power consumption of devices, or power generation from sources such as photovoltaic cells or wind turbines. In the example of power consumption, usage costs are calculated from user-defined tariffs. Conversely, for generation, the income from power generated is calculated.

At the completion of this project, the Wireless Power Monitor is capable of being deployed for use as a fully working prototype. In addition to this, the system provides a solid basis for future adaptation or expansion and due to its open source software can be easily modified for use in specific applications.
