Not getting consistent results with MQ gas sensors ...

· Goodevening...I am currently doing a project which involves MQ gas sensors. I have searched but have not found the answer that I was looking for. Has anybody know how to obtain consistent result with this sensor. When I use serial monitor to observe the behavior of the sensor, it keeps on fluctuating without getting any consistent values.

MQ2 - Reading different gases - Sensors - Arduino Forum

· MQ2 - Reading different gases. Hi all. I am using this code example from Sandbox Electronics to read from the MQ2 gas sensor. However, all my readings are 0. If I use a simple analog reading on the specific pin, I get the expected analog values - from 0 to 1023, usual values around 250, and if I expose it to gas for example goes up to 1000.

How to choose A Gas Sensor - GitHub Pages

We know that the air component is diverse, and a certain gas sensor can detect one or more air components, so we designed a series of gas sensor. There are about 10 kind of gas sensor for sale. They have similar name, it's likely to cause confusion. Hope that through the following presentation, we can help you to choose the appropriate gas sensor easily. It's obvious that different sensor can detect the same gas. Such as MQ-2, MQ-3, MQ-5, Alcohol Sensor, Grove – HCHO Sensor …
