Abstract

The consumption of electricity in Malaysia rapidly rises every year because of higher utilization of electricity in home appliances. The aim of this paper is to develop a prototype of a home electric usage notification & monitoring system using Nodemcu. The proposed system can notify and remotely monitor the energy usage consumption of the consumer in current, power, kilowatt hour and conversion of RM according to TNB Tariff. The existing electricity bill with all the information will be display through LCD on a prototype device itself and online monitoring features through smartphone. The system consists of Arduino Mega which interface with the current sensor where the sensor will detect the load current that went through the life cable. A programming part is created for the conversion from the sensor to the ampere. TNB tariff will be used as a reference to produce an electric bill and power which will be added in programming structure. The efficient way for the consumer to monitor their energy consumption, Nodemcu module will be used to make IoT device. Additionally, a relay will be added to the system where consumer able to control the appliances whenever the power usage is high for home appliances. This system helps the user to realize the amount of certain household appliances and manage the usage of it to save electricity. Furthermore, it would able to help users to plan their budget on coming month because without knowing the amount of electricity been used it will be hard for certain users to plan their budget.
