Smart Energy Meter Monitoring System (S.E.M.MS)

          Nowadays, energy management is one of most important things in today’s technology. A lot of people tend to work faster to get optimum results upon their career. We are doing project based on UTM Energy Management problem. From interview and all the questionnaire, we have decided on what project should we propose to fulfill end user requirement. We are proposing a device called ‘Smart Energy Meter Monitoring System’ (S.E.M.M.S). This device will monitor energy meter reading remotely.

          In term of Social aspect, system can still operate which mean it can provide real time data even the admin is busy working and data will be recorded in the application.

          Then, for Technology aspect, the use of NodeMCU as microcontroller and IoT device provide useful technology in our product. This can be deduced that the microcontroller can connect through internet via Wi-Fi and send the data to cloud database.

         Moreover, in Economy aspect, our S.E.M.M.S device can reduce manpower and also affordable with optimum outcomes. This is because firstly, our device can operate remotely without any meter readers. It also cost efficient as it is small in price and using cheap but quality materials.

        Furthermore, for Environment aspect, our project product is compact in size and adjustable to different types of meters. Meters come in any types of sizes and body. Our sensors enclosure can easily mount to any surface of meters based on its specifications. Lastly, in term of Political aspect, our system is absolutely legal to use and bring no harm to society.
