Mq 135 Gas Sensor

Sensitive for benzene alcohol smoke.

Mq 135 gas sensor.

Smoke detectors are very useful in detecting smoke or fire in buildings and so are the important safety parameters. The heater provides necessary work conditions for work of sensitive parts. The mq 135 gas sensor can detect gases like ammonia nh3 sulfur s benzene c6h6 co2 and other harmful gases and smoke. The heater provides necessary work conditions for work of parts materials.

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. Similar to other mq series gas sensor this sensor also has a digital and analog output pin. Structure and configuration of mq 135 gas sensor is shown as fig. Sainsmart 2 reviews sku.

Output voltage boosts along with the concentration of the measured gases increases. 31921952620623 mq 135 module is widely used in air quality control equipments for buildings offices are suitable for detecting of nh3 nox alcohol benzene smoke co2 etc. The air quality information is readable via the ao pin. Mq 135 gas sensor brand.

Structure and configuration of mq 135 gas sensor is shown as fig. The smoke sensor we used is the mq 135 sensor. 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. Increase decrease add to cart.

When the level of these gases go beyond a threshold limit in the air the digital pin goes high. 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. 5 49 2 5 29 3 4 99 4 share. The mq 135 gas sensor module has four pins standard male headers as shown above.
