I bought 5 capacitive moisture sensors. They came with about an 8" connector wire.
I'm wondering how long you can go from the Pi Irrigation Hat to the moisture sensor? Could I use 5 feet? 10 feet? More? Or is that too much of a voltage drop or maybe EMI causing trouble?
I could use the ESP8266 or similar, but wire is cheaper and quicker.
I'd probably use Cat5 Ethernet cable.
I run capacitive humidity sensors with Cat5 on 10m without problems.
I would like to know as well. I have the same distance to cover for my sensor as I do for the power wire to go to the valves, which is about 15m. I was going to just do some testing, but if anyone has some advice or experience that would be good
