Abstract:

In many processes it is important to have automatic control in the modern life. For example, a car can be automatically driven by computer through a software program and also sensors can be automatically controlled through a program. This project involves the development of microcontroller based MQ-4 gas sensor for domestic cooking gas system. The MQ-4 sensor has been used to detect the leakage of cooking gas which is mostly methane gas. Methane gas is flammable and very dangerous when used incorrectly. All gas manufacturing companies in the world resort to find secure methods which have low cost and are reliable to solve this problem. Most of these methods are using techniques which make the use of gas cooker systems safe. This project studies and shows one of simple way of calibrating the MQ-4 gas sensor using standard prepared solution of methanol. The calibration has been done so as to obtain optimum value for automation. Interfacing of the MQ-4 gas sensor has been done with Arduino UNO and other electronic components like buzzer, global system for mobile communications (GSM), subscriber identity module (SIM 900) and liquid crystal display (LCD). All these components are integrated and controlled by the Arduino UNO. The Arduino UNO controls all communication signals between these electronic instruments in this system through a developed program.
