In this project, we have designed Smoke Level Detector using MQ-135 Sensor for measuring the level of smoke in the environment. Simply we have interfaced MQ-135 Gas Sensor module with Relay and Buzzer. 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 which 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 Smoke level becomes higher than the desirable limit, this threshold value can be changed in the Circuit ?according to the requirement.
