| dc.description.abstract | In this project, a device load monitor for energy audit is designed to calculate the energy consumption of a load based on TNB Rating. An energy audit is a power consumption survey of the amount of units consumed by a particular device and the cost incurred. This device load monitor displays the power consumption of a device and estimates its electricity cost for 30 days. The monitor is equipped with a user-friendly interface that provides users with real-time information on the device's voltage, current, power consumed, and estimated cost. Additionally, users can customize the device load monitor by adjusting the tariff rate and number of hours the device is used per day. Users can upload the energy audit result to AppSheet as well for record purposes which will ease the progress of energy auditing. Overall, the device load monitor is a valuable tool for energy management, providing users with the flexibility to monitor and tailor their energy consumption to their specific needs. The voltage and current data validity are verified by comparing the data from the multimeter and the device load monitor when a varying AC input is supplied to a constant load. The average error percentage determined for voltage, current, and power consumed measurements is 2.16%, 12.24%, and 12.90% respectively. | |
