Package Includes: 1 piece x MQ 2 SMOKE Detector and Flammable Gas Sensor Module 

 

This is a very easy to use low cost semiconductor Gas sensor Module with analog and digital output. This module uses MQ2 Smoke & Flammable gas sensor as a gas sensing element. It requires no external components just plug in Vcc & ground pins and you are ready to go.

For Digital output the threshold value can be easily set by an on-board potentiometer.  Using this module you can easily interface MQ2 Smoke & Combustible gas Sensor to any Microcontroller, Arduino or even Raspberry Pi.

Since this Gas Sensor module is sensitive to smoke it can be used in for fire detection. MQ2 Gas Sensor is also sensitive to flammable/combustible gasses like LPG, Propane & Hydrogen.

Can be used as a Digital or analog sensor

Low Cost.

Stable & Long Life.

 

Applications:

Detects or measure SMOKE and Gases like LPG, Alcohol, Propane, Hydrogen, CO and even methane

Air quality monitor

Gas leak alarm

Safety standard maintenance

Maintaining environment standards  in hospitals

 

Selecting between Sensor type and module type:

When it comes to measuring or detecting a particular Gas the MQ series Gas sensors are the most commonly used ones. These sensors can either be purchased as a module or as just the sensor alone. If you are trying to only detect (not measuring ppm) the presence of a gas then you can buy it as a module since it comes with an op-amp comparator and a digital out pin. But if you planning to measure the ppm of a gas it is recommended to buy the sensor alone (without module).
