Project Description:

The LPG Gas Leakage Detector using Arduino, MQ6 sensor, OLED display, buzzer, and LED is a project that detects the presence of LPG gas in the environment and alerts the user. The project uses an MQ6 gas sensor to detect the presence of LPG gas. The sensor output is read by an Arduino microcontroller, which processes the data and displays the gas concentration on a OLED display. If the gas concentration exceeds a certain threshold, the Arduino triggers a buzzer and LED to alert the user.

Working Method:

The MQ6 gas sensor is connected to the Arduino microcontroller, which reads the analog output of the sensor and converts it into a digital signal using the built-in analog-to-digital converter. The Arduino then processes the data and displays the gas concentration on a OLED display. If the gas concentration exceeds a certain threshold, the Arduino triggers a buzzer and LED to alert the user.

To set up the project, you will need to connect the MQ6 gas sensor to the Arduino and calibrate the sensor using a known gas concentration. You will also need to connect the OLED display, buzzer, and LED to the appropriate pins on the Arduino. Once the hardware is set up, you can program the Arduino to read the gas sensor data, process it, and display it on the LCD display. You can also program the Arduino to trigger the buzzer and LED when the gas concentration exceeds a certain threshold.

Overall, this project provides a simple and cost-effective way to detect the presence of LPG gas using an Arduino and MQ6 gas sensor and alert the user using a buzzer and LED. It can be used in homes or small buildings to provide basic gas detection and safety.
