Description
The MQ-135 gas sensor detects gases like ammonia, nitrogen, oxygen, alcohols, sulfide, and smoke. The boost converter of the chip MQ-3 gas sensor is PT1301. The operating voltage of this gas sensor is from 2.5V to 5V. It has a lower conductivity compared to clean air and air pollution increases its conductivity.
