Co2 Gas Sensor Datasheet

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. When it comes to measuring or detecting a particular gas the mq series gas sensors are the most commonly used ones. The mq 135 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.
