LPG Sensor Module. Component Guide 3


mq6-gas-sensor-module2LPG Sensor modules are available now at low cost and we can use it in the Kitchen as a Gas leakage Alarm. The Module has a MQ6 Gas sensor, an Op-Amp as comparator and a preset for adjusting the sensitivity. All we need is a load resistor at the output to connect with the alarm circuit. Module is very sensitive to LPG (Liquefied Petroleum Gas) which contains Propane and Butane. The MQ6 sensor detects the gas concentration between 200 to 10,000 ppm.

Gas Sensors. How Stuff Works


Gas Sensors are devices which detects the presence of gases in an area. These are used for safety purposes to activate alarm systems as warning measure or to shut down a machinery. Gas detectors are used to detect different kinds of gases like combustible, flammable and toxic gases. These are also find application in the detection of oxygen depletion in an area. As the gas sensors measure a particular concentration of gas, the sensor responds to a calibrated gas and serves as a point or scale. As the level of gas increases above the sensor’s calibrated level, the alarm will be activated. Individual sensors are usually used to detect particular gases, but sensors capable of detecting various kinds gases are also available.

Gas Leakage Alarm using MQ 6 Sensor. Sensor Circuit.14


MQ 6 Gas sensor is used as LPG, Butane and Propane Sensor to generate alarm when there is leakage of these gases from the source. MQ6 is a highly sensitive gas sensor to petroleum based gases but less sensitive to Alcohol and Carbon di oxide. This simple sensor can be installed in the kitchen to give warning alarm if there is leakage of LPG.

Familiarize Electronic Components Part XVIII – Gas Sensors


Gas sensor is the device used for detecting the presence of Gases like Carbon monoxide, LPG, Ethanol, Toluene, Hydrogen etc. These are used as safety measures in work places and Home to avoid hazardous situations. The sensor can be used to generate an alarm or to activate a system to shut down the gas flow. Gas detectors are usually battery operated devices and if the gas level exceeds the preset level, it sends output signal to activate the circuit. Most commonly used gas sensors are LPG sensor, Smoke sensor and Alcohol sensor used in Breath analyzer.
