In-Depth: How MQ2 Gas/Smoke Sensor Works? & Interface it ...

· MQ2 is one of the commonly used gas sensors in MQ sensor series. It is a Metal Oxide Semiconductor (MOS) type Gas Sensor also known as Chemiresistors as the detection is based upon change of resistance of the sensing material when the Gas comes in contact with the material. Using a simple voltage divider network, concentrations of gas can be detected. MQ2 Gas sensor works on 5V …

How To Make Smoke Detector Alarm Circuit - Electronics Hub

· We used a Smoke Sensor MQ-2 as the main sensory device. The working of the circuit is simple and is explained below. LM358 acts as a comparator in this circuit. The inverting terminal of LM358 is connected to POT so that the sensitivity of the circuit can be adjusted. The output of LM358 is given to an LED as an indicator although a buzzer can be used as an alarm. The non-inverting …

How to Build a MQ-2 Smoke Sensor Circuit with a Raspberry Pi

MQ-2 Smoke Sensor Circuit Built with a Raspberry Pi. In this project, we will go over how to build a smoke sensor circuit with a Raspberry Pi. The smoke sensor we will use is the MQ-2. This is a sensor that is not only sensitive to smoke, but also to flammable gas. The MQ-2 smoke sensor reports smoke by the voltage level that it outputs. The more smoke there is, the greater the voltage that it ...

MQ-2 Gas Sensor + Arduino: How to Detect Dangerous Fumes ...

When the smoke concentration is above 1000 ppm, the circuit triggers a buzzer that can be changed in the code as required. This project uses the MQ-2 sensor and an Arduino to determine and detect different smoke intensities. This smoke detector can be easily built onto a breadboard or a polka dot plate. The MQ-2 sensor is used to detect the levels of gas around the area, so you can utilize ...
