How to Make LED Air Pollution Meter Circuit

In this project we are going 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.
