Electricity is one of the most vital blessings that science has given to humanity. It has many uses in the day-to-day life activities of human, which include, the lighting of rooms, powering of fans, televisions, and other domestic and industrial applications. The use of electrical energy provides comfort; on the other hand, the users of electrical energy needs to monitor the actual energy consumption (kWh) and wastage (kVAR) in an electrical appliance. The traditional postpaid energy meter used for measuring the consumption of consumers do not offer such facilities. The coming of the smart energy meter (SEM) was expected to provide an enhanced service to consumers of electric energy; however, the current stage of the SEM does not offer daily consumption alert to consumers, neither does it permit the user to set a threshold value for daily or monthly consumption cutoff. This work sought to design and construct an automatic electrical load monitoring, control and alert system using an Arduino UNO (Atmega328p) microcontroller, which offers real-time alert to users on their energy consumption with no additional wiring work required. An implementation of the proposed system provided efficient monitoring, control and warning of electrical energy consumption as compared with the traditional energy meters. |
