In this project, we have designed Arduino Smoke Level Detector using an MQ-135 Sensor for measuring the level of smoke in the environment. Simply we have interfaced the MQ-135 Gas Sensor module with Arduino and 16*2 LCD module for display. The Smoke sensor we used is the MQ-135 sensor. Smoke Detectors are very useful in detecting smoke or fire in buildings, and so are the important safety parameters.

Smoke Detector Circuit not only senses the smoke in the air but also reads and displays the level of Smoke in the Air. This circuit triggers the Buzzer when the Smoke level becomes higher than the desirable limit, this threshold value can be changed in the Code according to the requirement. Instead of MQ-135, you can use MQ2, MQ3, MQ5 modules as well. Basically, they all have similar functions.
