Automated Hazardous Gas Detecting Robot using Wireless Sensor Networks with GSM-SMS Alert and Fire Control System for Households

Abstract

Over the past decades, fire cannot be prevented in our homes and society. Hence, the author came up with an idea to create a robot that will serve as first responder to fire and hazardous chemicals. Problems were identified and objectives were formulated as guides in the establishment "Automated Hazardous Gas Detecting Robot using Wireless Sensor Networks with GSM-SMS Alert and Fire Control System for households". This robot is designed having two wheeled drive navigation to easily move and detect hazardous substances and fires. It is equipped with gas sensor to monitor if there is a gas leakage in a room and is programmed to automatically send messages to the registered number using GSM Module. It was installed to be able to send Short Messaging Service (SMS). This paper is about a microcontroller based project, with microelectronics devices, namely, Flame Sensor (KY-026), GSM Module (SIM 900A), gas sensor (MQ-2), L293D Motor Shield, a 12V DC motor and 12V DC Water Pump, Arduino UNO, a light emitting diode (LED) and a buzzer. These were carefully programmed and patiently tested to ensure its working conditions. Through well-planned design, data gathering and testing its reliability, the author came up with an automated detection system in a robotic application with features like SMS notification, an alarm system and extinguishing fire. The author concluded that this project is reliable and can help the homeowners secure their home from the blazing disaster brought by fire and hazardous gases.
