Abstract:
Waste of energy is a problem of practical significance that occurs in most
conventional buildings. The world energy consumption is expected to increase up to
50% by 2030. One of the effective ways to increase the awareness of the building's
energy consumption among the occupants is through monitoring the energy
continuously. This project proposed the development of a real time energy monitoring
data logger using Raspberry Pi for monitoring the building's energy consumption. The
project started from designing the system infrastucture with all the components are
gathered and setup with Raspberry Pi 3. The connecting process between the
Raspberry Pi and all of the component is completed if there is no problem on the
components and Raspberry Pi. Then, the development of coding through python script
is completed when there is no syntax and logic error. Lastly, final testing on the
project is carried out. If there is any problem occurred, then overall testing and
troubleshoot will be repeated on the problem until the problem is solved.The main
system comprises of an SCT-013-000 Current Transformer (CT) sensor, RPICT3Tl
CT sensor adaptor and a Raspberry-Pi as a central processing unit. Other related
components used are buzzer, LED indicator and speaker works as an alert device,
whereas hard disk used for storage of logged data. An alert system can send E-mail
and text messaging to notify the user about their daily consumption that exceeded the
limit. From the testing of the final complete system, it shows that energy can be saved
significantly through controlled usage of loads. This is because the system
continuously monitoring the energy usage data and send the alert to the user when
their usage exceeded the limit specified.
