    Hello! Can I know if anyone has tried using the board for this sensor with the MQ137 Ammonia sensor? The design is practically almost the same and the pins are similar too.

    Hello! Can anyone tell me how I would go about heating up the sensor? I know that I need to apply power to the sensor between 24-48 hours (based on the datasheet), my question is,do I have to apply gas (I was planning on using a lighter for this part)

    Would I be able to remove the MQ2 on this board and replace it with an MQ8?

    Hi there, We are not sure that MQ8 would work well with the board, but you can try. Because we didn't test the MQ8 before.
