Air Quality Sensor Using Arduino

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.

You will be able to use this Arduino Air Quality Monitor indoors to measure pollution from cooking, smoking etc., and outdoors to measure the air quality of your neighbourhood. Air Quality Sensors. The most common type of air quality sensor that measures PM2.5 uses a laser to detect particulate matter.

Hello, In this tutorial based article, we are going to learn how to build an Air quality monitor using Arduino. Hardware Required Arduino Uno. DHT11 temperature sensor. MQ135 air quality sensor. Jumper cables. Software Required Arduino IDE. Nowadays

here inside the mq9 sensor they are using the filament made by the co reactive element which reacts with the co. and in the presence of the co the conductivity will vary with thee carbon monoxide. that's why we are getting the different value in this air quality monitoring system project.. Gas Detection The MQ-9 sensor is only designed for detecting carbon monoxide CO and some of the

DIY Arduino air quality monitor which can measure surrounding air quality also shows temperature and humidity in your room. Air Quality sensor MQ135 Tools and machines. 1. 3D Printer generic 1. Soldering iron generic Apps and platforms. 1. Arduino IDE. Project description. Code.

In this step-by-step tutorial, you will learn how to build a simple air quality monitoring system using Arduino. Learn the basics of AQI and how air quality sensor works. We have also given the circuit diagram and Arduino code to help you build on your own.

The sensor is using non-dispersive infrared principle for measuring CO2 in the air. An infrared source directs light through a tube which is filled with the air that we are measuring. DIY Arduino Air Quality Monitor - Circuit Diagram. Nevertheless, so let's take a look at the circuit diagram now and explain how everything needs to be

The complete air quality monitoring system project connection will be as follows with an OLED, DHT11 and MQ135 gas sensor connected to Arduino Uno on a breadboard. The arduino is connected to the OLED using I2C protocol with the help of the SDA and the SCL pins.

Here the variables used for the Air Quality Sensor The variables for the Air Quality Sensor. Now, it's up to the Dust Sensor. The PM Particulate Matter level in the air is measured by counting the Low Pulse Occupancy time LPO time in given time unit, that is proportional to PM concentration. This sensor is responsive to PM of diameter 1m.

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. Block Diagram of Air Pollution Monitoring System using Arduino and MQ135
