GAS Sensor

The GAS Sensor project demonstrates how to interface a gas sensor with an Arduino Mega to detect and measure gas concentrations. This project utilizes an analog gas sensor to detect the presence of gases in the environment and calculate their concentration in parts per million (ppm). It provides a method to monitor air quality or detect specific gases based on sensor readings and threshold settings.

Instructions

Install Required Libraries:

No additional libraries are required for this project.

Circuit Setup:

Connect the gas sensor module to the Arduino Mega as specified in the circuit setup section.

Code Upload:

Open Arduino IDE and create a new sketch.

Copy and paste the provided Arduino code into the sketch.

Testing:

Upload the code to the Arduino Mega.

Open the serial monitor in Arduino IDE to view the sensor voltage and calculated gas concentration (ppm).

Observe the serial monitor for gas detection notifications based on the predefined threshold.
