Manufacturing low-cost wifi-based electric energy meter

The meter calculates power consumption and electric energy demand. Measurements are done through a microcontroller-based circuit. Data is sent through wireless wifi connection to a web server. Wireless capacity is provided by a wifi router. The construction process could be summarized in three steps. First, a sensor circuit based on a microcontroller was built. Second, telemetry capacity was developed. Last, a web server was designed. The web server is a modification of a software originally used to monitor mesh network radio links. Measures are visualized as power versus time or energy versus time.
