Mq 2 Gas Sensor Datasheet

Structure and configuration of mq 2 gas sensor is shown as fig.

Mq 2 gas sensor datasheet.

The mq 6 gas sensor can detect or measure gases like lpg and butane. 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. 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. The module version of this sensor 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.

For the detailed information about the mq 2 sensor please refer to the datasheet. When the target combustible gas exist the sensor s conductivity is more higher along with the gas concentration rising. The mq 2 gas sensor can detect or measure gasses like lpg alcohol propane hydrogen co and even methane. There are lpg cylinders which are used as a fuel source for the gas stove.

Where to use mq 6 gas sensor. For detail information about the mq 2 sensor please refer the data sheet provided in resources section. Many a times disastrous accidents take place due to leakage of these cylinders in these situations we must administer proper care and safety. 300ppm 5000ppm h2 100ppm 2000ppm alcohol d.

The heater provides necessary work conditions for work of sensitive components. Mq 2 semiconductor sensor for combustible gas sensitive material of mq 2 gas sensor is sno 2 which with lower conductivity in clean air. 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. 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. Structure and configuration of mq 8 gas sensor is shown as fig. The output voltage from the gas sensor increases when the concentration of gas increases.

The gas the bigger the output voltage of the sig pin. Mq 2 mq 5 aq 2 mq 306a aq 3. Sensitivity can be adjusted by rotating the potentiometer.
