DaguRobot MQ-135 Sensor Detecting Module

• MQ-135 Sensor Detecting Module by DaguRobot
• Detects Air Quality (Concentration of CO2, Alcohol, Benzene, NOx, Ammonia, etc.)
• Working Voltage: 3.3 V
• Output Type: Digital signal, Analog signal
• Interface mode: ph2.0 – 4p

The DaguRobot MQ-135 Sensor Detecting Module detects air quality (concentration of CO2, alcohol, benzene, NOx, ammonia, etc.). It comes with two outputs digital signal and an analog signal. It runs on a 3.3 V working voltage and the interface mode is ph2.0 – 4p.

Note: MQ-135 can detect all the gases listed above, but cannot distinguish them. If you want to target one gas specifically, it is best to choose another sensor. The sensor also requires a heater to warm up the sensor. It is not recommended to use it with a smaller battery, as it will quickly run out of battery power.
