Now a day’s, safety and precaution of LPG gas leakage detection is needed or must in daily life. And technology is rapidly running for the stopping the incident which happened in the kitchen, commercial as well as industries by gas leakage. Here we work for detect the LPG gas as well as measure it. The gas will detect as well as measure continuously and display the measure on display and send communication via SMS to the user. And it will also detect the measure of remaining gas at a certain Kgs. The sound will be notify by alarm as well as message will give preciously suggestion to user and user can prevent it. Proposed of this project is notify the alerts to users before any incident.
Keywords: LPG gas leakage detector, LPG gas monitoring, wireless sensor network gas sensor GSM module, MQ-6 Gas sensor, Load Sensor, Signal Amplifier.
The LPG (Liquid Petroleum Gas) can be leaked in different forms like gaseous liquid aspects. This project is likely used to continuously monitoring and detecting the weight of LPG gas and leakage LPG gas. As we observe may times that, whenever LPG gas cylinder is empty then we have to give request at last moment and due to the shortage of cylinder. We did not get cylinder on time and we have to face some critical conditions. So by monitoring LPG gas cylinder we can give request to LPG service provider before gas is 25% remaining then on a lower priority SMS will send is send to owner and again it SMS is send to owner on high priority at 10% . On many places we heard about GAS leakage news. It also detects Gas leakage by using detecting sensor. When LPG gas is leakage then gas will be detect and SMS is send to owner. It will be helpful to everyone and we could take prevention on it.
2. Literature survey
Shivalingesh B.M, Ramesh C, Mahesh S.R, Pooja R, Preethi K. Mane, Kumuda S. Department of Instrumentation Technology BMS College of Engineering, Bangalore-19, India. Volume I, Issue VI, November2014 IJRSIISSN 2321 -2705. “LPG Detection, Measurement and Booking System.” In this paper we present how to detect the leakage using a gas sensor and book a new cylinder automatically by sending a message to agency. The gas sensor MQ-6 is very sensitive to methane and propane which are main constituents of LPG. A load cell is used to measure the weight of cylinder continuously. The weight of cylinder is displayed continuously and some 4-5 MQ-6 sensors will be placed in different place of room, output of sensor will become high when there is LPG leakage is present. When the sensor output is high buzzer will be switched on and a message will be sent to customer and nearest gas agency via GSM. When the weight of cylinder equal to threshold value a message will be sent to agency to book new cylinder. The same system is implemented using Lab VIEW, and a statistical analysis of gas sensor and load cell is done.

This unit can be easily integrated into a unit that can sound an alarm. The sensor has great sensitivity and rapid response time. This sensor can also be used to sense other gases like iso-butane, propane and even cigarette smoke. The output of the sensor goes LOW as soon as the sensor senses any gas leakage in the atmosphere. This is detected by the microcontroller and buzzer is turned on. After a delay of few milliseconds, the exhaust fan is also turned on for throwing the gas out and the main power supply is turned off. A message ‘LEAKAGE’ is sent to a mobile number that is predefined.
Liquid Crystal Display module:
The liquid crystal display (LCD) unit is a video display that develop light modulation to display several outputs such as picture or text on a screen. The LCD displays have developed considerably to be included in wide variety applications since their inventions in 1964. In this work, a 16 × 2 LCD unit is employed to be assigned as the sight that demonstrates the resultant data. The number 16 × 2 is attached to the display module refers to show the data on 16 columns and 2 rows. The proposed LCD module is chosen due to its quite compatibility with the Arduino. The amount of data realized by the sensors are reported through the microcontroller and revealed on the LCD module as information. For simplicity, the connection scheme between the LCD module and the proposed microcontroller which is shown in Figure3 was done in Fritzing software.
MQ-2 Gas Sensor Module:
Liquefied Petroleum Gas (LPG) or the sensitive material of MQ-2 gas sensor is SnO2 considered as lower conductivity in the clean air. The conductivity of the sensor shown in Figure4 gets higher as long as gas concentration is elevated. The sensitivity of MQ-2 sensor is considered exceptionally higher to propane, LPG, hydrogen, methane, and the other steams. Moreover, the cost limitation of the proposed sensor is assigned to be appropriate for numerous applications.
The sensor realizes the flammable gas by an increase in the temperature when excited by the heating components. As a working principle, when gas leak is detected the conductivity of the sensor gets higher proportionally with gas concentration raising
Gas Leak Control System:
The whole system is proposed to be home-used application under the supervision of the microcontroller with respect to MQ –2 gas sensor. The control system was designed to serve as monitoring center that detects and applies control action on the realized situation by the sensor module. As a background, the system is considered controllable since it satisfies the block diagram methodology shown in Figure.
X: The input signal.
Y: The output signal.
G1: The uncontrolled system (Plant). G2: The processing block (Sensor).
H: The feedback of the system (Controller).:
Sdis: The disturbance signal.
The components shown in Figure 6 can be illustrated as the uncontrolled environment G1 or the plant as called in control system is the portion that contains all the possible situations that can happen. Sdis is the unexpected signal which can invade the environment that is the term
represented by gas leak in this work. G2 or the sensor is the part responsible for updating system controller with latest changes in the environment and feed the system back as controller input. Finally, the most popular part is the term H, which leads the whole environment to its quite – desirable condition. In this work the plant would be the house environment that needs to be under the supervision of the controller. The system shown in Figure7 represents the entire schematic connection and the interaction of the controller with the environmental changes. The proposed module in this work is constructed of Arduino UNO microcontroller, LCD unit, SIM900 GSM shield, Relay module, MQ –2 gas sensor, and an air puller Fan alongside with a buzzer used as alarm system. The working principle of the module starts normally with no gas leak in the environment, making the control system in an idle situation. Once gas leak is detected, the whole module will be put in charge to start monitoring and supervising the situation.
When the gas sensor is excited by leakage signal the controller triggers the relay module by PWM signal from the microcontroller to take the action by turning the alarm system and the relay ON synchronously in order to allow the AC power to flow through the Fan and pull the gas out of the environment accordingly. Occasionally, the matter was proposed to be vice versa with the elimination of the gas leak problem. Simultaneously, an automatic signal excites the GSM
shield to broadcast the condition of the environment as an SMS to a corresponding phone number. Finally, the LCD module is employed in the system in order to demonstrate gas leak situation on the 16 × 2 character introducer alongside with the GSM module.
We have used Liquid crystal display (LCD display) for continuously monitoring the weight of the LPG Gas cylinder. Here we are used 16×2 alphanumerical displays. It can used to display the current status of the Gas cylinder. it can also be used to display the output of the system. LCD display can show the weight of the gas cylinder at a same it can display the various MSG like “Gas Leakage”. When our system is ON then the MSG will be display on the LCD is “System ON” and when there is no gas leakage occurred then the MSG display on the LCD is” System secure”. When leakage is occurred then MSG on LCD are “System insecure”.
Weight sensor module:
The weight sensor we used is the load cell module. A load cell is described as a “weight measurement device necessary for electronic scales that display weights in digits.” However, load cell is not restricted to weight measurement in electronic scales.
Load cell is a passive transducer or sensor which converts applied force into electrical signals. They are also referred to as “Load transducers”. Load cells use different operating principles, viz.
- Load Cells based on fluid pressure
- Load Cells based on elasticity
- Load Cells based on magnetostriction effect or piezoelectric effectHowever, the only load cells which are prevalent are the load cells based on strain gages. Hence, the term ‘load cell’ means ‘strain gage-based load cells’. The reason behind the wide adoption of strain gage-based load cells is their characteristics
- Highly precise and linear measurements
- Little influence due to temperature changes.
- Small size compared with other types of load cells.
- Long operating life due to lack of moving parts or any parts that generate friction.
- Ease in production due to small number of components.
- Excellent fatigue characteristics
A cost effective gas leakage detection system is successfully completed in this paper. A huge loss has to be cured for the accidents by leakage. This project is used in domestic as well as industrial purpose. Additionally, it activate an alarm or buzzer and send SMS to owner.
