✅ Smart Air Quality Monitoring Using the MQ-2 Sensor

How can we measure the air quality of the environment and determine whether it is healthy or polluted?

In this article, we will teach you how to build a functional module for monitoring the air quality of your environment and displaying the air status on a screen. By further developing this project, you can create a much more advanced air quality monitoring system, ensuring that the air in your home or workplace is always under control and healthy.

So, let’s first take a look at the tools and components required for this project.

1 – ATmega8 SMD Microcontroller

2 – MQ-2 Sensor Module

3 – Nokia 5110 Display

4 – LM35 Temp Sensor

5 – Perfboard (Dot Matrix Board)

6 – A few XH Connector Sockets

You can purchase each of these components from our website store. Click the link below to visit the store.

Now, it’s essential to get familiar with the MQ-2 sensor. To do so, we recommend watching the video below.

Now that you’ve familiarized yourself with this module in the video above and have received explanations about the circuit, you can download the project files and codes below, build the circuit, and start using it.

It’s important to note that you can further develop this project to make it more advanced, enabling it to control devices like air purifiers to keep the environment clean and healthy. By doing so, you would essentially create a functional air purification device that could be monetized by selling it.

Even in its current state, you can build this module and sell it through our store, your own outlets, or platforms like Amazon to generate income. Nowadays, monitoring air quality and ensuring clean air in homes or workplaces has become a necessity.
