How to Make LED Air Pollution Meter Circuit with Arduino

Last Updated on December 5, 2024 by Swagatam 3 Comments

In this project I will show how to construct an air pollution meter using MQ-135 sensor and arduino. The pollution level in the air is indicated by series of 12 LED. If higher the number of LEDs glows, the higher the pollution content in the air and vice versa.   Overview This project can prove […]
