MQ-2 Smoke LPG Butane Hydrogen Gas Sensor Module

If you are searching for a gas sensor module with a very high detection range compared to any ordinary gas sensor, then this MQ-2 Smoke LPG Butane Hydrogen Gas Sensor Detector Module will fulfill your specification demands. The MQ-2 gas sensor detector module has a detection range of 300-10000 ppm. The gas sensor modules are always well known for their robust and simple construction and measure toxic gases in very low concentrations. The MQ-2 Smoke LPG Butane Hydrogen Gas Sensor Detector Module is useful for gas leakage detection (home and industry). It is suitable for detecting H₂, LPG, CH₄, CO, alcohol, smoke, or propane. Due to its high sensitivity and fast response time, measurements can be taken as soon as possible. The sensitivity of the sensor can be adjusted by the potentiometer. The MQ-2 gas sensor using gas-sensitive material is to be clean air in the lower conductivity of stannic oxide or tin oxide (SnO₂). When the sensor detects flammable gases present in the environment, the conductivity of the sensor with an increasing concentration of combustible gas in the air increases. Use a simple circuit to convert the changes in conductivity and output signal that correspond to the concentration of the gas. The MQ-2 gas sensor's higher sensitivity to liquefied petroleum gas, propane, hydrogen, detection of gas, and other combustible vapors is ideal. This sensor can detect a variety of flammable gases and is a low-cost sensor for many applications. The following conditions must be avoided: Water Condensation Indoor conditions and slight water condensation will affect sensors’ performance lightly. However, if water condensation is on the sensor's surface for a certain period, the sensor's sensitivity will be decreased. Used in high gas concentration No matter if the sensor is electrified or not, if it is placed in a high gas concentration for a long time, it will affect the sensor’s characteristics. Long-term storage The sensor’s resistance produces reversible drift if it’s stored for a long time without electrifying; this drift is related to storage conditions. Sensors should be stored in an airproof bag without silicone gel with clean air. For the sensors with long-time storage but no electrification, they need a long aging time for stability before using. Longtime exposed to an adverse environment No matter if the sensors are electrified or not, if exposed to an adverse environment for a long time, such as high humidity, high temperature, or high pollution, etc., it will affect the performance of the sensor badly. Vibration Continual vibration will result in the sensors' down-lead response and then rupture. In transportation or assembling lines, a pneumatic screwdriver/ultrasonic welding machine can lead to this vibration. Concussion If a sensor meets a strong concussion, it may lead to its lead wire being disconnected. Explore more gas sensors; click the link Gas Sensor Application: 1.
