GSM Operated Circuit Breaker with Fire Sensor

Abstract

In the Philippines, fire is one of the most potent disasters man has ever encountered. One major cause of this is the overloading and overheating of circuit breakers. Circuit breakers and fuses are not guaranteed to prevent short-circuit fires such that fire incidents that razed residential premises, buildings, and institution are considerably causing massive damage to properties and loss of lives. The researchers utilised a prototype circuit breaker to be operated using the Global System for Mobile (GSM) Communication Shield Module with fire sensor, a device that controls the electricity flow through text messages and can notify the user about the device’s status. It also comes with built-in fire sensors to automatically break the circuit and alert the user whenever fire is present. It is operated by texting the GSM Communication Shield Module the duration of how long the user wants to run the electricity in the circuit. The device is mainly composed of the Arduino® Uno Board, a GSM Communication Shield Module, and a relay. The researchers also created a code to run the device. Connections were secured in a rectangular box. The device was also tapped in a prototype circuit. A survey was conducted to determine users’ acceptability on the device and to test the device’s functionality. The device got an overall rating of 4.5275 on its acceptability, and 4.87 on the functionality. This study showed that the device is highly acceptable and functional; thus, the device can help reduce fire incidents and conserve energy.
