Mq 2 Gas Sensor Datasheet

For detail information about the mq 2 sensor please refer the data sheet provided in resources section.

Mq 2 gas sensor datasheet. Mq 2 semiconductor sensor for combustible gas sensitive material of mq 2 gas sensor is sno 2 which with lower conductivity in clean air. The mq 2 gas sensor can detect or measure gasses like lpg alcohol propane hydrogen co and even methane. Mq 2 mq 5 aq 2 mq 306a aq 3. 1 configuration a or b sensor composed by micro al2o3 ceramic tube tin dioxide sno2 sensitive layer measuring electrode and heater are fixed into a parts materials 1 gas sensing.

Sensitivity can be adjusted by rotating the potentiometer. Please use simple electrocircuit convert change of conductivity to correspond output. Structure and configuration basic measuring circuit structure and configuration of mq 2 gas sensor is shown as fig. Sensitivity can be regulated by rotating the potentiometer.

Please note the best preheat time of the sensor is above 24 hours. Structure and configuration of mq 8 gas sensor is shown as fig. 1 configuration a or b sensor composed by micro al2o3 ceramic tube tin dioxide sno2 sensitive layer measuring electrode and heater are fixed into a crust made by plastic and stainless steel net. Where to use mq 6 gas sensor.

The mq 6 sensor module comes with a digital pin which makes this sensor to operate even without a microcontroller and that comes in handy when you are only trying to detect one particular gas. The mq 6 gas sensor can detect or measure gases like lpg and butane. 300ppm 5000ppm h2 100ppm 2000ppm alcohol d. For the detailed information about the mq 2 sensor please refer to the datasheet.

Structure and configuration of mq 2 gas sensor is shown as fig. There are lpg cylinders which are used as a fuel source for the gas stove. 1 configuration a or b sensor composed by micro al2o3 ceramic tube tin dioxide sno2 sensitive layer measuring electrode and heater are fixed into a parts materials 1 gas sensing layer sno2 2 electrode au 3 electrode line pt 4 heater coil ni cr alloy. Many a times disastrous accidents take place due to leakage of these cylinders in these situations we must administer proper care and safety.

When the target combustible gas exist the sensor s conductivity is more higher along with the gas concentration rising. The heater provides necessary work conditions for work of sensitive components. The output voltage from the gas sensor increases when the concentration of gas increases.
