Davide Gironi: MQ gas sensor correlation function ...

· · I just successfully managed to reproduce your setup using a pre mounted board named FC-22 with the MQ135 on it. 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 …

· · MQ131: TGS2600: Where I’m unclear is I don’t know if turning the resistance wheel I would raise the resistance or lower it, but in every case I see two issues: 1- managing the resistance is not equivalent to calibration. 2- if a sensor reboot while being in a polluant atmosphere with this method of initial calibration, it will report 0 all the time… on the opposite doing the ...

Manual -

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 ...

MQ131 Ozone Gas Sensor Module - Cytron Technologies

MQ131 Ozone Gas Sensor Module is a compact board based on the MQ-131 sensor. It is equipped with a very wide range sensitivity to ozone which able to detect ozone concentration up to (10~1000ppb) in ambient air. The tin dioxide (SnO2) is the sensor's sensitive material, has a low conductivity (high resistance) in a clean air environment, and react really good in a presence of ozone. Thus ...
