The Grove - Gas Sensor(MQ2) module is useful for gas leakage detecting(in home and industry). It can detect LPG, i-butane, methane, alcohol, Hydrogen, somke and so on. Based on its fast response time. measurements can be taken as soon as possible. Also the sensitivity can be adjusted by the potentiometer.
Hot-swapping the grove may lead to IC burnout, please turn off the power of main board before swapping grove.
More information about gas sensor, please refer to this manual.

Is this module compatible with LinkIt ONE?
I am a noob in this field. Can you tell me what is the working range (in m) of MQ2 sensor? Like will it be able to sense smoke from 1m away?
Hello! i have a question, how i can get the value in ppm or %? I follow the instructions that the wiki describe, but i have values like:
After i put the R0 value into the other code, and it show me this values:
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.
Hi, i want know about the value recollected what is the measured unit
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?
