I've purchased the MQ2 Smoke Detector Shield for Arudino, and I found out that there's no official datasheet for this product.

I was wondering if you could send me anything that could help me in order to use the shield properly.
All I want to do is to measure concentrations of gases in the air. I need to convert the analog input value to PPM.
