This is a continuation of my previous post on control system v4.0. In that post I wrote about the hardware. Now I will talk about the software. If you have been following my drip irrigation control system design, you know that I switched from Arduino to ESP8266. It took some time for me learn about the new board, but it is very similar to Arduino when it comes to programming it.

One was a way to access the system via internet, so I don't need to physically configure it. And the other was to add a humidity sensor. I finally worked on the first upgrade. Now my control system is accessible over the net (currently limited to my home network). However, I had to make a few hardware design changes. I replaced Arduino with ESP8266. The why and how follows.
