Davide Gironi: Cheap CO2 meter using the MQ135 sensor with ...

26/04/2015· I get a reading of 1kohm between the left bottom of the sensor and Analog out of the board. I tried to infer the resistance from adding a small 40 ohm resistor to it but the Rs value out of it and the response seems a bit unstable and inaccurate as it falls to 140ppm. I get values that shoot up to few thousand at times (For CO2). Possibly I do have a different curve, but I tried with a second ...
