· The board comes with a pull-down resistor of 1k and some other features for digital reading. I would like some help regarding my readings. My Raw measurements tend to fall between 36 and 40 on a closed environment. For these values I get between 374ppm and 504ppm. It seems the ppm values vary too much for very small changes on the raw readings and since raw data can range from 0-1023 …

MQ131 Test Circuit Instructions: The above fig is the basic test circuit of sensor requires two voltage inputs: heater voltage (V H) and circuit voltage (V C). V H is used to supply standard working temperature to the sensor and it can adopt DC or AC power, while V RL is the voltage of load resistance R L which is in series with sensor. Vc supplies the detect voltage to load ...

· As you might noted, the enveloped MQ-135 have 6 pins – 4 of them are used to fetch signals, and other 2 are used for providing heating current. Here, the series resistor (5R1) in the module schematic (Fig 3) is not very crucial, but the load resistor (1K in the schematic) is essential. As mentioned, its value should be in the 10K -47K range.
