Interfacing of MQ-135 Gas Sensor with Arduino

When no gas digital output is 1 and analog output gives 1023 max value. When gas is present digital output is 0 and analogue output is much less than 1023. Using potentiometer on chip we can control the turning OFF point of digital pin at some value of analog pin. The sensor needs a load-resistor at the output to ground. Its value could be from 2kOhm to 47kOhm. The lower the value, the less ...

Air Quality Sensor | MySensors Forum

2014-08-03· A sensor module like the MQ-135 has an analog output voltage, which you can feed to an analog input of your Arduino. Most modules also have a digital output, which can be tuned using the onboard potmeter, which triggers when a certain level has been reached. These sensors come calibrated (to a certain amount) but calibrating them yourself will be complicated as you need to replicate an ...
