Abstract
Minimising energy wastage is vital for economic development. This paper deployed a web-based design and implementation of smart electric home appliances control, which enable owners to remotely use web access to efficiently control their home appliances energy usage. Node MCU, breadboard, light emitting diodes (LED), relays, resistors, electric wires, Wi-Fi device (smart phone, tablets or computer), jumper wires, transistor, direct current (DC) motor, universal serial board (USB) cable, printed circuit board (PCB), C programming language and Arduino IDE (Integrated Development Environment) were used, for circuit design and implementation. C programming codes were written and compiled in Arduino IDE device, then uploaded into Node MCU through USB cable to control energy usage of electrical appliance (DC motor) connected to the circuit. The control was achieved by turning ON the DC motor when needed and OFF, when not in use, remotely via web. Whenever appliance was OFF, LED showed red color and green LED lights up when appliance was ON. Developed control system performed excellently and efficiently by significantly minimizing energy wastage, when appliances are not in use. Future research should consider smart home control systems able to record quantities of energy consumed at any period of the day.
