Abstract

The project study entitled Microcontroller-based Automatic Standby Power Trimmer focuses on the development of an automatic power shut-off device especially designed for areas wherein a number of computers are used. The device will be named Automatic Standby Power Trimmer since it trims down unnecessary standby power. One primary aim of the study is to solve the problem regarding unnecessary power consumption when unused computers are left on standby. This study also included further analysis on the drawbacks of standby power. Principal application of the device is on computer laboratory rooms of the College of Engineering Architecture and Technology of the university and computer shops comprising of utmost 20 computers. Its principle of operation is to turn off a single main supply after the predetermined time based on the hours of usage of the computer laboratory room and computer shop. The device however, will not go into automatic shut-off when at least one of the computers within the room is still in use, provided that the remaining computers are still in standby. A manual override feature which immediately switches the main line off was also added. This override feature works only under the condition that all the computers involved are in standby and none of them is in use. Moreover, the study also comprise of the power consumption analysis of the computers treated as samples under both the condition wherein the Microcontroller-based Automatic Standby Power Trimmer was used and wherein no such device was applied.
