Automated Hazardous Gas Detecting Robot using WSN 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.
? In the existing method, there are different gas sensing technology is used. Semiconductor sensor is used to detect the LPG gas leakage.
? The already existing communication module enables the sending of measured gas level data and the alarming signals of the hosted gas sensors unit.
? In existing methods only the leakage detection is done but there is no way of controlling it.
? There exist only alerting the user regarding the level in the cylinder but there isn’t any automatic booking of the cylinder.
? The major problem in residential areas, industrial sector and CNG (compressed natural gas) gas-powered vehicles like buses, cars is Gas Leakage.
? There are already some kinds of corrective measures, such as when the leakage is detected; message is sent to the fire station and the owner and this technique has the disadvantage that it requires manual control, which puts people in immediate danger when no control action is taken.
? The other remedial measure is that when the leakage is detected, the exhaust fan is switched ON and it has the disadvantage that improper cabling of the exhaust fan causes immediate explosion due to AC flow.
• The proposed work focuses on the systems that can measure the concentration of specific hazardous (toxic, poisoned, and noxious) gases even if it is part of the hybrid system (e.g., fire, smoke, personal safety, fall detection, and so on.).
• Our proposed system is to monitor the gas level and automatically book the gas when the gas level is reduced.
• The system detects the leakage of the LPG using gas sensor and alerts the user about the gas leakage by sending SMS using the gsm module and additionally if the user is not available the gas regulator is automatically turned off.
? The hybrid sensing elements may use different manufacturing/detection technologies/methodologies, which enhance the performance and increase the reliability and sobriety of the system.
? The robotic implementation is the closest and most credible form of the word “mobile” especially for indoor applications where the drones/quadcopter offer similar advantages to robots for outdoor applications.
? This concept offers a cost-effective and highly efficient system that not only detects gas leakage but also alerts (alarms) and turns off the primary supply of energy and gas and sends an SMS.
