DEVELOPMENT AND ACCEPTABILITY OF AN OFFICIAL SCHEDULE-BASED CONTROL OF ELECTRICAL CIRCUITS

Abstract

The main thrust of the study is to develop a device/system that is designed to control and
manage the use of electrical devices and sources in classrooms based on prescribed class
schedules. The device/system was used to control the convenience outlets, lighting, and
electric fans situated in the classroom. The system may be programmed within any duration as
the administrator sees appropriate which may be within a week to as long as a whole
semester. The system will automatically manage the electrical circuit based on the programmed
schedule. During unscheduled use of the classroom, the occupants shall not be able to operate
any of the electrical facilities inside the room.
After assembly, the system was implemented using the high current control, programmable
control, override, and electronic noise filter sections. The system was subjected to periodic
observation by the researcher to ensure functionality and reliability. Based on the cost-benefit
analysis conducted by the researcher, the system can significantly reduce the electric
consumption of the University if fully implemented. The system was deemed to be very
acceptable by its potential end-users.
To further enhance the study it is recommended that to ensure the optimum operation of the
system, a technician may be assigned for its regular maintenance. Future researchers may
modify the system by adding more features like a remote control to easily program the
schedules. The device may be installed inconspicuously to avoid unauthorized handling.
