Circuitrocks Mq-2 Mq-3 Mq-4 Mq-5 Mq-6 Mq-7 Mq-8 Mq-9 Mq-135 Smoke Methane Liquefied Gas Sensor Modul

 

MQ135 gas sensor sensitive material used in the clean air, low conductivity tin oxide (SnO2). When present in the environment pollution gas sensor, conductivity sensor with the increase in air pollution in the gas concentration increases. Use a simple circuit can convert the change in conductivity of the gas concentration corresponding to the output signal.

 

MQ-2 gas sensor sensitive material used in the 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. Using a simple circuit to convert the change in conductivity of the gas concentration corresponding to the output signal.MQ-2 gas sensors 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, are a low-cost sensor for a variety of applications.

 

MQ - 3 gas sensor is used in clean air low conductivity tin oxide (SnO2). When there is alcohol vapor in the environment sensor, the conductivity sensor with an increasing gas concentration of alcohol in the air increases. Use a simple circuit can convert the change in conductivity of the gas concentration corresponding to the output signal. High MQ-3 gas sensor sensitivity to alcohol, can resist the interference of gasoline, smoke, water vapor. The sensor can detect a variety of alcohol concentration in the atmosphere, is a low-cost sensor suitable for a variety of applications

 

MQ - 4 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 a simple circuit can convert the change in conductivity of the gas concentration corresponding to the output signal. MQ-4 Methane gas sensor of high sensitivity, propane, butane, and has good sensitivity. The sensor can detect a variety of combustible gases, especially natural gas, it is a low-cost sensor suitable for a variety of applications.
