Anyone that has been out to the farm or that knows me at all knows that I love to do things with Arduinos and Single Board Computers.  As a good friend has said on many an occasion I am the only person that he knows that is actually making and deploying real IoTs.   Now, while I do think that this statement is a bit of an exaggeration I don’t disagree with him.  A few months ago I ordered a few of these CH340G wifi enabled boards from one of the usual places (I think I got them from aliexpress but I I am not 100% sure).  They are cheap as all get out, so I won’t care if a cow steps on one, but with a bunch of digital pins and a single analog pin as well as SPI there really isn’t much that can’t be done with these little boards.  I have a SBC in one of the hen houses right now that is controlling the light as well as serving a small web page that displays the current temperature and humidity inside the hen house.  I am thinking that I should swap that out for one of these boards because they are far,far more robust to the enviroment and they are about 5% of the cost of the SBC and memory card that is currently in the hen house.  I have a feeling that I will be firing up KiCAD in the next few days to design a PCB for this project.
