Mq 135 Gas Sensor Datasheet

Selecting between sensor type and module type.

Mq 135 gas sensor datasheet.

The mq 135 gas sensor module has four pins standard male headers as shown above. After the sensor is energized it needs to be preheated for about 20s and the measured data is stable. The heater provides necessary work conditions for work of sensitive parts. Simply we have interfaced mq 135 gas sensor module with arduino and 16 2 lcd module for display.

The smoke sensor we used is the mq 135 sensor. 1 xmq135 air quality sensor module. The heating of the sensor is a normal phenomenon because there is a heating wire inside. Smoke detectors are very useful in detecting smoke or fire in buildings and so are the important safety parameters.

Structure and configuration of mq 135 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. 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. Mq 135 gas sensor pinout features alternatives datasheet uses guide.

Structure and configuration of mq 135 gas sensor is shown as fig. Mq 6 aq 2 mq 306a aq 3. Since ao is a varying voltage this pin should be connected to one analog input of a microcontroller the do pin is an open collector digital output but with a pull up resistor onboard that becomes low when the detection level exceeds a predefined level. The function is gas sensor.

When it comes to measuring or detecting a particular gas the mq series gas sensors are the most commonly used ones. These sensors can either be purchased as a module or as just the sensor alone.
