MQ6 – LPG Propane Gas Sensor
The MQ-6 LPG - Isobutane - Propane Gas Sensor is a semiconductor gas sensor that detects the presence of LPG, Isobutane, and Propane gas at concentrations from 100 ppm to 10,000 ppm, a range suitable for detecting gas leaks. The sensor’s simple analog voltage interface requires only one analog input pin from your microcontroller.The MQ-6 LPG - Isobutane - Propane Gas Sensor detects the concentration of gas in the air and outputs its reading as an analog voltage. The sensor can operate at temperatures from -10 to 50°C and consumes less than 150 mA at 5 V.
MQ6 – LPG Propane Gas Sensor Module
MQ7 – Carbon Monoxide (CO) Gas Sensor
MQ7 is a Carbon Monoxide (CO) sensor, suitable for sensing Carbon Monoxide concentrations(PPM) in the air. MQ7 Gas sensor can measure CO concentrations ranging from 20 to 2000 ppm. This sensor has a high sensitivity and fast response time. The sensor's output is an analog resistance.This sensor comes in a package similar to MQ3 alcohol sensor. MQ7 gas sensor has high sensitivity to Carbon Monoxide. The sensor could be used to detect different gases contains CO, it is with low cost and suitable for different application. They are used in gas detecting equipment for carbon monoxide(CO) in family and industry or car.
MQ7 – Carbon Monoxide Gas Sensor Module
MQ8 Hydrogen H2 Gas Sensor Module
This sensor module has an MQ-8 as the sensor component and has a protection resistor and an adjustable resistor on-board. A sensitive material MQ-8 Hydrogen H2 Gas Sensor Module use in 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-8 hydrogen gas sensor of high sensitivity, the monitoring of the other hydrogen-containing gas is also very satisfactory.
This sensor can detect a wide range of hydrogen gas, city gas, in particular, is a low-cost sensor for a variety of applications.
Suitable for home or industrial hydrogen leakage monitoring devices. Can not interfere with ethanol vapor, soot, carbon monoxide, and other gases.
MQ9 Carbon Monoxide, Methane and LPG Gas Sensor Module
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.
