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.

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?
