Ever wanted to measure soil moisture? Common “soil moisture meter module arduino raspberry compatible free shipping” PCBs might deceive you with their ascetic looks.

Implementation of LoRaWAN-based soil moisture sensing device. (Credit: Maja Škiljo et al., 2022) Although we generally think of Internet of Things (IoT) and similar devices as things that are ...

There are a bunch of Arduino-compatible boards that have more memory to work with than a standard Uno, so if you're running low on memory space you might consider switching to one of those.

I'm planning to have a "spider" of moisture sensors off one Arduino - 5 or 6 coming off one box. Again, I doubt you need continuous monitoring even with multiple sensors.
