Developmwnt of a real time energy data logger using raspberry pi for monitoring the building's energy consumption

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.
