MQ2 Gas Sensor Module Smoke Butane Methane Detection

The MQ2 Gas Sensor Module is a robust and reliable device designed to detect the presence of smoke, butane, and methane in the environment. It's an essential tool for ensuring safety in various settings. 

MQ-2 gas sensor sensitive material used in the clean air low conductivity tin oxide (SnO2). When there is the environment in which the combustible gas sensor, conductivity sensor with increasing concentration of combustible gases in air increases. Using a simple circuit to convert the change in conductivity of the gas concentration corresponding to the output signal. MQ-2 gas sensor high on gas, propane, hydrogen sensitivity of detection of natural gas and other flammable vapors are also very good. This sensor can detect a variety of flammable gas, is a low-cost sensors for a variety of applications.

This product has the MQ sensor carrier board included. Works with 5V and has TTL level digital and analog outputs which makes it very easy to use with Arduino and other microcontrollers.
