IOT based Intelligent Gas Leakage Detector Using A Circuit Diagram Working of lpg gas leakage detector. Here we are using an MQ2 gas and smoke sensor module to detect the leakage of smoke, Propane, Hydrogen, Carbon monoxide, and methane. When the gas comes in contact with the sensing material inside the sensor its resistance changes. Many accidents occur in day to day life like explosion because of LPG leakage. Major harm is caused, if gas leakage is not detected early. But now we can detect the gas leakage using the MQ5 gas sensor. In this IOT gas leakage detector, device will get connected to WIFI, the minimum and maximum parameter can be set accordingly.
In conclusion, this tutorial guides users through the creation of a gas leakage detector using the MQ2 sensor module and Arduino Uno. The MQ2 sensor's sensitivity to various gases, including LPG, alcohol, propane, hydrogen, methane, and carbon monoxide, makes it a versatile choice for gas detection. To test the gas leak detector with Arduino and Blynk IoT project, we exposed the hardware design to gas emmsion from a cooking gas cylinder. Once the gas started erupting, the MQ-2 gas sensor pictked up the smell and the design could be seen beeping a warning sound.

In this case, when a gas leak occurs, it is detected by the MQ2 sensor. Then the buzzer and LED are activated. At the same time, it notifies your smartphone via a push notification. Also, we can see the gas values on the LCD and Blynk app interface. In the absence of a gas leak, the green LED bulb turns ON and operates normally in this security Produce a sound alarm upon gas leak and stop the alarm once gas leak is under control (gas presence in atmosphere is under normal range) Display status in an LCD using a 16ร2 LCD module. A gas sensor is a device which detects the presence or concentration of gases in the atmosphere.
In this project, we will build Gas Leak Detection & Alarm System using MQ2 Gas Sensor and Arduino UNO Board. The MQ2 sensor is a versatile gas sensor capable of detecting a wide range of gases as well as smoke. This initiative is centered on creating a mock-up of a gas leak detection system utilizing an Arduino Uno as the core controller. We use node MCU as a microcontroller or a wifi development board that reads the analog values from the gas sensor. In the code, we set the gas value [200]. The node MCU sends these analog values to the Smartphone to the Blynk application. when the gas value gets increased above 200 the app shows the notification "Gas Detected". In the visual editor window, choose and change your Gas Leak sensor and the devices where you want to send notifications. For instance, the above-shared automation code sends a notification alert to our Android or iOS device and also announces the voice alert via Alexa speakers (Echo Dot and Echo Show devices installed in the house) when the
