ABSTRACT
This paper presents the design and implementation of a digital energy meter with a remote transceiver that will accurately measure and calculate the amount of energy consumed by a certain facility while displaying its cost. The energy meter provides the utility company and consumer with regular status of the meter on a predefined interval and also disconnects the facility when requested so as to increase the efficiency of energy management. The meter, having a measuring capacity of minimum and maximum loads of 2 mA and 80 A respectively, could increment time with its inbuilt timer and counter subsystem in the microcontroller based on the embedded system code written into it. The meter with its communication facility aided with SIM800l module could be remotely monitored and controlled. This was demonstrated by sending off, on and watts commands via SMS. The energy meter responded to the commands as expected.
