Guide for MQ2 Gas Sensor with Arduino | Random Nerd Tutorials

· Example: Gas Sensor with Arduino. In this example, you will read the sensor analog output voltage and when the smoke reaches a certain level, it will make sound a buzzer and a red LED will turn on. When the output voltage is below that level, a green LED will be on. Parts needed: So, for this example, you’ll need: 1 x MQ2 gas sensor


How to Build a MQ2 Smoke Sensor Circuit with a Raspberry Pi

This is a sensor that is not only sensitive to smoke, but also to flammable gas. The MQ2 smoke sensor reports smoke by the voltage level that it outputs. The more smoke there is, the greater the voltage that it outputs. Conversely, the less smoke that it is exposed to, the less voltage it outputs. The MQ2 also has a builtin potentiometer to adjust the sensitivity to smoke. By adjusting the ...
