You can download the datasheet of this module here.[wpdm_package id='18191'] ...

MQ-2 Smoke Gas Module Features MQ series sensor uses a small heater inside with an electrochemical sensor in order to measure a different kinds of gas combinations. They can be calibrated, but, in order to do that, a known concentration of measured gas or gases is necessary. Gas sensor is an indoor module and is used at room temperature. The MQ-2 sensor is suitable for the detection of butane, methane, alcoholic, LPG and smoke. It is also sensitive to ignition and combustion of gases. Note Afte...

MQ-7 Smoke Gas Module Features MQ series sensor uses a small heater inside with an electrochemical sensor in order to measure a different kinds of gas combinations. They can be calibrated, but, in order to do that, a known concentration of measured gas or gases is needed. Gas sensor is an indoor module and is used at room temperature. The MQ-7 sensor has high sensitivity to Carbon Monoxide and is able to detect the concentration of carbon monoxide in the air. The measurable concentration range of this s...

MQ-8 Hydrogen Gas Sensor Features MQ series sensor uses a small heater inside with an electrochemical sensor in order to measure a different kind of gases combinations.
