MQ-2 Gas Sensor tests - Page 1

2019-11-06· I've been measuring the resistance of an MQ2 sensor, trying to get something like the tempco results shown in the DS. This is a sensitive device, and something like a breeze (eg from a hairdryer) massively alters results. I can't be sure, but I think the net effect of the hairdryer (no cold setting!) is to lower the surface temperature of the ZnO sensor. However, also tried holding sensor …

Using the MQ136 Sensor - Sensors - Arduino Forum

2021-05-06· I just received a SainSmart MQ136 Semiconductor Sensor for Hydrogen Sulfide, which is a sensor attached to a little board. This is different from a lot of the gas sensors I've seen online that don't come with the board. I'm not exactly what this is called and what purpose it serves, but I guess it contains things to make it easier to use. It also has a potentiometer on the back, but since I ...
