mq131 beginner - Sensors - Arduino Forum

2021-05-06· The MQ-131 requires 100k (50k to 500k) as load resistor. The other sensors use lower values. I have not tested a MQ-131 myself, therefor I don't know how it behaves. I'm not sure if I have the sensor somewhere. 2 days preheat is okay. Perhaps the resistor value (the "load resistor") is too low. If it drops down to fast to zero, increase the value of the resistor. After studying the datasheet ...
