My WiFi doesn't reach the pond, and I'll need to connect the Raspberry Pi to the internet, but I think I found a workaround that will hopefully function in order to get internet out there.
A long time ago, when I was 8, I ran electricity out to the detached garage that previously had no power. The pond runs off the garage power, and the garage is ran off the same circuit breaker box as the house, so I'm thinking I'll use one of those powerline Ethernet adapters from inside the house to send the Ethernet signal over the electrical line. It works by transmitting the signal at a frequency very different from that of the AC power, at about 2-86 megahertz as opposed to the 50-60 hertz frequency of the alternating current. I just hope that there isn't too much signal degradation. I don't need super fast internet out there anyway, as I just need to upload telemetry, and be able to access the admin interface from my computer inside of the house.
I was thinking I'd use a Raspberry Pi Zero, but I'm thinking I'll probably just spend the extra money on a regular Pi 3, as it has an Ethernet port, and I don't want to take up GPIO for an Ethernet port that would be needed for the pH and temperature probes. I'm planning on getting a pH sensor from Atlas Scientific, and I'm going to use a DS18B20 temperature probe.
So far, planning this project has been easier than I initially thought it would be, so hopefully it won't be too hard to put together.
keep us updated please!
