Abstract

This research study entitled "S.A.F.E Outlet (Sensor Activated Failsafe Extension)": An Arduino-based sensor-activated electrical outlet aimed to evaluate the development and determine the effectiveness of the device for household appliances and other devices and its acceptability among experts and users as a basis for technology adoption during the school year 2025-2026. The study involved 30 respondents consisting of students and parents of Giloctog National High School. An experimental method and descriptive quantitative method were utilized for the study using a purposive sample method for the respondents to measure the acceptability of the device. This study found out that there is no significant difference in temperature readings in comparison with the infrared thermometer; however, the minor variations between measurements of both devices could be attributed to improper shielding from electromagnetic interference and the use of non-calibrated sensors as the basis for this device. The S.A.F.E. outlet reacted faster to smoke than any commercially available smoke alarms under high CO concentration levels, hence demonstrating a clear advantage of being able to prevent fire disaster. The water detection system reacted much more quickly to moisture than conventional moisture testers, therefore providing an increased level of safety for avoiding electrocution. Independent t-tests confirmed that the differences between the S.A.F.E. outlet and commercial testing devices were statistically significant. Furthermore, the acceptability assessment revealed a very high level of user approval across different age groups, genders, and occupations, having an overall weighted mean of 4.34 (5 stars ★★★★★, outstanding rating); respondents strongly recommended the S.A.F.E. outlet as a failsafe device for everyday use.
