*MQ2 Smoke Gas Sensor Module
- is a general purpose gas sensor able to detect LPG, butane, methane, alcohol, hydrogen, and smoke. This sensor has a high sensitivity and fast response time. The module outputs a voltage from 0 to 5V relative to the gas concentration.


*MQ3 Alcohol Gas Sensor Module
- MQ3 Alcohol Gas Sensor Module is used for detecting alcohol concentration on your breath, like a Breathalyzer. This sensor has a high sensitivity and fast response time. The module outputs a voltage from 0 to 5V relative to the alcohol concentration.

Specifications:
•Concentration : 0.05 mg/L ~ 10 mg/L Alcohol
•Operating Voltage : 5V ±0.1
•Current Consumption : 150mA
•Operation Temperature : -10°C ~ 70°C

Pin Out:
•VCC – Input Power Supply
•GND – Supply Ground
•DO – Digital Output
•AO – Analog Output

*MQ4 Methane Gas Sensor Module
- MQ4 Methane Gas Sensor Module is a Compressed Natural Gas Sensor (CNG), which is mostly made up of methane (CH4), it is suitable for sensing natural gas concentrations in the air. The MQ4 can detect natural gas concentrations anywhere from 200 to 10000ppm.


*MQ6 LPG Gas Sensor Module
- This sensor has a high sensitivity and fast response time. The module outputs a voltage from 0 to 5V relative to the gas concentration.


*MQ7 Carbon Monoxide Gas Sensor Module
- MQ7 Carbon Monoxide Gas Sensor Module is used to detect Carbon Monoxide (CO) concentration, it can detect CO-gas concentrations anywhere from 20 to 2000ppm. This sensor has a high sensitivity and fast response time. The module outputs a voltage from 0 to 5V relative to the CO concentration.


*MQ8 Hydrogen Gas Sensor Module
- MQ8 Hydrogen Gas Sensor Module is suitable for sensing hydrogen concentrations in the air. The MQ8 can detect hydrogen gas concentrations from 100-10000ppm.

*MQ-5 Liquefied Gas Methane Gas Sensor Module
-The Simple MQ-5 Methane LPG Liquid Propane Gas Sensor Module is a great way to add basic gas sensing to your project at a reasonable price. TheMQ-5 Methane LPG Liquid Propane Gas Sensor Module particulate sensor uses a Buzzer to sense any detected material that is even present in the air!

*MQ-9 gas sensor module has high sensitivity to Carbon Monoxide, Methane and LPG. Sensitive material of MQ-9 gas sensor is SnO2, which with lower conductivity in clean air. It makes detection by cycling high and low temperature, and detects CO when low temperature (heated by 1.5V). The sensor’s conductivity is higher along with the gas concentration rising. When temperature rises (heated by 5.0V), it detects Methane, Propane, combustible gas, etc and cleans the other gases as it adsorbed under low temperature. MQ-9 usually pplied in domestic gas leakage detector, industrial gas detector, portable gas detector, etc. Waterproof, X-ray proof, temperature proof, and shockproof
