Here is my "promo" video of sorts. My hope is that it will help others to understand the motivation and application behind the project. I am pretty happy with the way it turned out :)
I am still on the hunt for a proper sensor suite to replace the MQ2. I definitely want to make the unit capable of measuring all the standard gas and air quality levels that are used for commercial units. As the cost on these is extremely high I may just mod the code as mentioned before to give a strict go/no-go indication of levels with the MQ2 as the invidual level reporting doesn't work well when the sensor is overwhelmed.
Let me know what you think of the video and project. Take the design and make it better!
