IoT power monitoring device using Wi-fi and Arduino

Reliable real-time power measurement data represents a vital role in understanding energy behavior from a consumer standpoint. Energy efficiency is directly influenced by monitoring electric parameters. With collected live data, the challenge becomes how to organize and analyze datasets of information. The purpose is to design and build a low-cost electronic monitoring device using Arduino and IoT for electricity monitoring. The main capabilities are to measure, record, and transmit using wi-fi connection all the essential electric parameters in a web-based application. Monitored electric parameters are voltage, current, power factor, phase angle, power, and energy. The developed prototype is versatile in multiple types of low voltage installations, mainly household appliances. Measurements are transmitted remotely in an online database, where the data can be stored and analyzed in realtime. The solution has permanent storage and facilitates consultation of past and current records. The market approach is possible because of the low-cost of the device. A commercial version would be suitable and could easily integrate Smart Grid applications. Using real-time energy data and monitoring software, consumers can measure high consumption loads, reduce base loads, evaluate peak and off-peak hours and identify irregularities. Optimize usage scheduling and track energy-saving targets and goals more accurately.
