The Development of a Prototype Gas Stove Safety System for Residential Buildings Using Embedded Systems Technology

Abstract

The objectives of this research were to 1) develop a prototype safety system for household gas stoves using an embedded system technology, 2) evaluate the efficiency of the prototype system, and 3) assess user satisfaction with the prototype system. The prototype system consists of two main components: a main control unit and a gas leakage detection unit. The system operates in both automatic and user-controlled modes, with functions including scheduled operation and on/off control and visual and audible notification system. The prototype is developed using an Arduino Uno R3 board, an MQ-6 gas sensor, a gas solenoid valve, a keypad, an LCD display, an audible and LED notification. System performance evaluation includes unit testing with four functions and system testing with four functions, as well as a study of user satisfaction with the prototype system. The statistical methods used for data analysis included mean, percentage, and standard deviation. The results showed that the efficiency of the prototype based on unit testing achieved 100% on all 4 functions which are gas dispersion over the distance, automatic gas shutoff, automatic operation scheduling, and gas concentration alert notification at 400 ppm. Similarly, the system testing results also demonstrated 100% efficiency on all 4 functions which were gas dispersion over distance, automatic gas shutoff, automatic operation scheduling, and gas concentration alert notification at 400 ppm. Furthermore, user satisfaction rate of the prototype system was at the highest level, with an average score of 4.57 and a standard deviation of 0.52
