MQ135 Gas Sensor Pinout, Features, Alternatives ...

+

· MQ135 is available as a module or as just the sensor alone. If you are trying to only detect (not measuring PPM) the presence of a gas then you can buy it as a module since it comes with an opamp comparator and a digital output pin. But if you planning to measure the PPM of a gas it is recommend buying the sensor alone without module. Where to use MQ135 Gas sensor. The MQ135 …

Interfacing of MQ135 Gas Sensor with Arduino

+

Interfacing of MQ135 Gas Sensor with Arduino: In today’s world, we encounter different scenario where we see different gasses being emitted in atmosphere such as home appliances like air conditioner and industrial chimneys. Monitoring of these gasses is very important with safety point of view. Gas Sensors are very helpful in accomplishing this task.
