Technological Proposal for Measuring Electric Parameters in Households

摘要

One way to supervise energy consumption, as well as guaranteeing the correct billing and delivering of the electric service is to monitor several electric parameters in the network and present them in a intelligible way. This article shows the design and implementation of a prototype capable of indirectly measuring electric variables present in a residential installation, with the purpose of monitoring and showing the value of each parameter to a subscribed user while storing the energy consumption data from up to 30 days so they can be visualized in a interface. The prototype is based on an Arduino embedded system, which is in charge of handling data for voltage, current, energy and power. Additionally, the Arduino system is synchronized in real time with a clock, an external memory crucial for validation and an LCD touchscreen that serves as an interface for the analysis of data acquired and the display of variables in real time. In particular, the measuring device has pressure error lower than 1.72% when compared to the reference instrument used in experimental testing which reveals the optimal operation of the prototype.
