What is the maximum length of cabling between the sensor and the controlling computer? I'm putting this on a boat and would like to be able to have the sensor about 10ft (3m) from the computer.

Hi there~ You can use two Grove- RJ45 adapter and one network cable to connect this sensor to your control board. By this way, it could be 3m or even longer. Regards ================================================================= http://wiki.seeedstudio.com/Grove-RJ45_Adapter/

Is this compatible with Wio Link? It doesn't seem to work with mine when configured as a Generic Analog Input device. Keeps the board from powering up.

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.
