Gas Detection and PPM Measurement using PIC Microcontroller and MQ Gas Sensors

MQ series Gas sensors are very common types of sensors used in Gas Detectors to detect or measure certain types of Gases. These sensors are widely used in all Gas related devices like from simple Smoke Detectors to Industrial Air Quality Monitors. We have already used these MQ gas sensors with Arduino to measure some harmful gases like Ammonia. In this article, we will learn how to use these gas sensors with PIC Microcontrollers, to measure the PPM value of the gas and display it on a 16×2 LCD.

Smoke Detector Circuit

This smoke detector  circuit triggers the Buzzer whenever it detects Smoke or fire near by it. This circuit mainly uses MQ6 Smoke/Gas sensor to detect the level of smoke
