Gas Leakage Detection using Node Microcontroller Unit

Explosions caused by gas leaks are become a major hindrance to living in our country. It is crucial to use technology whenever it is available because it is currently altering the world. By employing LPG gas, we can use technology to stop mishaps from occurring in the future. The system, which is built on a Node MCU, makes use of buzzer, Thing speak, and gas sensors. It is intended to be used in conjunction with a DHT11 and MQ135 sensor as a monitoring and alert system for LPG gas leakage. The MQ135 gas sensor and node MCU make up this circuit. The sensor will alert the microcontroller if a gas leak is detected. Before displaying, the microcontroller bases its decision on such details. The main objective of this project is to create a workable prototype that can detect gas leaks, namely leaks of liquefied petroleum gas (LPG). When the leak is found, the device should also immediately react by putting in place an alert system and an emergency shut-off valve. Finding leakage is the most crucial part of this research, and leakage is found by monitoring variations in infrared radiation intensity . When this circumstance arises, both the alarm and the emergency shutoff valve will be turned on. Additional study is being done, namely to comprehend certain information about infrared radiation detectors, LPG properties, alarm and relay circuits.
