In this tutorial, we'll build a complete gas monitoring system using Arduino that includes Real-time gas level detection LCD display integration 5-LED
Connect MQ-135 sensor's VCC pin with 5V terminal of Arduino UNO. This will power up the sensor. Additionally, we will connect the analog pin AO with A0 and DO with Pin 2 of Arduino UNO. Both the devices will be commonly grounded. Follow the connection diagram below, to connect your devices accordingly.
Arduino is the main microcontroller board of this system. The gas sensor continuously measures air quality and sends data to the Arduino board. Then Arduino prints air quality value on the OLED display in the PPM unit. The LEDs and Buzzer used as indicators, that indicates the air quality is in good, Poor, or dangerous zone.
In our case, it is A4 pin of the Arduino UNO board. Create another variable named sensorData. We will use this variable to store the data that will be received by the Arduino from the sensor. void setup Serial.begin9600 pinModesensorPin,INPUT Inside the void setup block, set the baud rate for the serial communication and initiate

How to connect the MQ-135 Gas Sensor with Arduino? Let's discuss the project plan and connect the MQ-135 Gas Sensor with Arduino. The story is simple. We will connect the MQ-135 gas sensor with Arduino to detect Gas. If the sensor picks unusual Gas in the environment, we will start a buzzer as an alarm. We can also send SMS using the GSM module.
Before getting started you must know about MQ-135. MQ-135 is a gas sensor which is sensitive to CO2. The change in CO2 levels changes the resistance of sensor which results in the change in the output of the sensor. The output generated from the sensor is feed to Analog Input to Arduino board In my case Arduino Uno.
In this tutorial, I will provide the essential details about the air quality index, the pinout of the MQ-135 sensor, and how to measure air pollution using the MQ-135 sensor. After this tutorial, you will be able to develop the air pollution monitoring and alert system using the Arduino Uno board with an MQ-135 sensor.
