I'm trying to set up a system to get the water temperature at the end of a pier, to a base station in a house nearby. Maybe 150 meters?
I was planning to use an Arduino connected to one of these thermometers:
And then send the data wirelessly to the base station in a boathouse near the end of the pier. Issues:
Because of tides and storm surges, the wire on the temperature probe would have to be about 30 feet long. The stock cord is 6 feet. Does anyone know if I can safely extend that?
for the wireless transmission, I've got a 950mhz Feather from another project. Can I use two of those for point-to-point communication? Or would something like a Zigbee be better? Here's the Feather I have:
- the data is going to be read by a Raspberry Pi eventually. I can do that via an Arduino of course, but it would be nice if I could skip that and go directly into the Pi.
Incidentally, here's a live camera aimed at the pier:
The temperature probe would go at the end of it, since that's where the power lead is.
