Abstract/Executive Summary

This study presents the development and evaluation of AutoSwitch: An Automated Classroom Power Control System with Occupancy-Based Activation and Timed Deactivation, a system designed to improve energy management in classrooms by combining ultrasonic occupancy sensing with time-controlled power deactivation. The study aimed to determine the effectiveness of AutoSwitch in activating and deactivating classroom power, the accuracy of occupancy detection, the system’s response time, and overall operational reliability. An experimental research design was employed, where controlled occupancy scenarios and scheduled time intervals were used to evaluate system performance across multiple trials. Data were collected on successful activation and deactivation of the solid state relay, occupancy detection accuracy, false detection rate, and response time from detection to switching. Results indicate that the system successfully activated classroom power in 86.25% of occupancy events during allowed hours and maintained complete deactivation during restricted hours, achieving a 100% success rate. The ultrasonic sensor achieved an occupancy detection accuracy of 86.88% and a low false detection rate of 13.13%. The average response time for activation ranged from 1.08 to 1.15 seconds, while deactivation remained instantaneous. The system achieved an overall reliability rate of 93.13% across 160 activation and deactivation trials. These findings demonstrate that AutoSwitch provides a reliable, efficient, and practical solution for automated classroom power management, reducing reliance on manual switching and promoting responsible electricity usage.
