MQ-4 (Methane Gas Sensor module for Arduino)

Gas sensor MQ4 registers presence and concentration of natural gas and methane (CH4). The best results are given when gas is in liquid form, however, since situations like this are rare, it does its job pretty well when in gas form, too. It needs a bit of time to warm up in order to work correctly.

MQ-6 LPG Gas Sensor Module

This is a simple-to-use liquefied petroleum gas (LPG) sensor, suitable for sensing LPG (composed of mostly propane and butane) concentrations in the air. The MQ-6 can detect gas concentrations anywhere from 300 to 10000ppm. This sensor has a high sensitivity and fast response time. The sensor’s output is an analog resistance. The drive circuit is very simple; all you need to do is power the heater coil with 5V, add a load resistance, and connect the output to an ADC.

MQ-7 (Carbon Monoxide Gas Sensor Module)

MQ-7 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. The sensor can operate at temperatures from -10 to 50°C and consumes less than 150 mA at 5 V.

MQ-8 (Hydrogen Gas Sensor Module)

Sensor Modules, Barometric Pressure Sensor

MQ-8 Sensor Information: sensitive material MQ- 8 gas sensors used in clean air, low conductivity tin oxide (SnO2). When there is an environment in which the combustible gas sensor, conductivity sensor with increasing concentration of combustible gases in air increases. Use simple circuit can convert the change in conductivity of the gas concentration corresponding to the output signal. MQ-8 hydrogen gas sensor of high sensitivity monitoring of other hydrogen-containing gas is also very good. The sensor can detect a variety of hydrogen-containing gas, in particular, city gas, is a low-cost sensor suitable for a variety of applications.
