MQ2 to MQ135 Gas Sensor.

MQ2, MQ3, MQ4, MQ6, MQ7, and MQ135 are all types of gas sensors widely used in various applications for detecting different gases in the environment. Each sensor is designed to detect specific types of gases and operates based on different principles.MQ2 is primarily used for detecting gases such as methane, propane, hydrogen, alcohol, and smoke. It operates on the principle of gas conductivity, where the conductivity of the sensor changes when it comes into contact with the target gas, leading to a corresponding change in resistance.MQ3 is designed to detect alcohol vapors in the air, making it suitable for applications such as breathalyzers and alcohol detection systems. It also operates on the principle of gas conductivity similar to MQ2.MQ4 is specifically designed for detecting methane gas, making it suitable for applications in gas leak detection systems, methane detectors, and industrial safety equipment. It operates based on the principle of gas sensitivity, where the presence of methane gas alters the conductivity of the sensor.MQ6 is a gas sensor primarily used for detecting LPG (liquefied petroleum gas) and propane. It operates on the principle of gas conductivity, where the sensor's resistance changes in the presence of these gases.MQ7 is designed for detecting carbon monoxide (CO) gas, which is highly toxic and can be produced by incomplete combustion of carbon-containing fuels. It operates based on the principle of electrochemical detection, where the concentration of CO gas in the air causes a change in electrical conductivity within the sensor.MQ135 is a versatile gas sensor capable of detecting a wide range of gases including ammonia, nitrogen oxides, benzene, smoke, and CO2. It operates on the principle of gas sensitivity, where the presence of target gases alters the conductivity of the sensor, allowing it to detect different gases with high sensitivity.
