Mq 135 Gas Sensor Datasheet

Structure and configuration of mq 135 gas sensor is shown as fig.

Mq 135 gas sensor datasheet.

These sensors can either be purchased as a module or as just the sensor alone. The heater provides necessary work conditions for work of sensitive parts. 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. Selecting between sensor type and module type.

The function is gas sensor. Mq 135 hoja de datos mq 135 datasheet hanwei gas sensor hoja técnica mq 135 pdf dataark wiki arduino regulador amplificador circuito distribuidor. Structure and configuration of mq 135 gas sensor is shown as fig. The function is gas sensor.

The heater provides necessary work conditions for work of. 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 mq 135 gas sensor module has four pins standard male headers as shown above. 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.

After the sensor is energized it needs to be preheated for about 20s and the measured data is stable. Smoke detectors are very useful in detecting smoke or fire in buildings and so are the important safety parameters. Simply we have interfaced mq 135 gas sensor module with arduino and 16 2 lcd module for display. Mq 135 gas sensor pinout features alternatives datasheet uses guide.

The smoke sensor we used is the mq 135 sensor. Mq 1 1n4 2n2 2sa 2sc 74h adc bc bf bu cxa hcf irf ka kia la lm mc ne st stk tda tl ua. The mq 135 gas sensors are used in air quality control equipments and are suitable for detecting or measuring of nh3 nox alcohol benzene smoke co2. The air quality information is readable via the ao pin.

The function is gas sensor. The heating of the sensor is a normal phenomenon because there is a heating wire inside.
