EASY Plug MQ-135 air quality sensor gas detection module for Arduino STEAM
MQ135 sensor uses SnO2 sensitive material because SnO2 has low electrical conductivity in the clean air; when surrounded by polluted air, conductivity increases with increase of pollutants, and change can be converted to corresponding output signal
Rotate the potentiometer on the sensor to adjust the sensitivity
MQ135 has a high sensitivity to ammonia, sulfide, benzene vapor, smoke and other harmful gases; target gas: ammonia, methylbenzene, hydrogen
Should be used together with EASY plug control board; interface Easy plug, sensor type Semiconductor, operating voltage 5V DC, load resistance Adjustable RL, quick response and high sensitivity, 56x20x18mm, 9.2g

Overview

The MQ135 uses SnO2, which conducts little in clean air and more as pollutants rise, and that change is turned into an output signal. Sensitivity is set with the onboard potentiometer; it responds strongly to ammonia, sulfide, benzene vapor, and smoke.
