The study aimed to control and monitor household power outlets by using Global System for Mobile Communication (GSM) through Short Message Services (SMS). The researchers developed a device that could reduce power consumption within the household by controlling and monitoring the power outlets. The project consisted of three major parts: PIC16F877A microcontroller, relays, and GSM module. The microcontroller, as the brain of the project, converts the signal from the GSM module to turn the power outlets “ON” or “OFF” as well as to check their current status (ON/OFF). The GSM module receives and sends data to and from the microcontroller to control and monitor the household’s power outlet through SMS. Relays, on the other hand, gets feedback and triggers power outlets.
The proponents used descriptive and experimental research methods to gather data. The preliminary data were collected from observations, experimentations, testing, and discussions from people who shared their ideas and knowledge for the project’s development. The secondary data were gathered from books, magazines, journals, and unpublished and published theses and dissertations from various institutions.
The study showed that Global System for Mobile Communication (GSM) is a possible transmission medium for controlling and monitoring of household power outlets remotely.
