I'd probably use one module to run 5 or 6 sensors, conformal coated and buried. I'll do some shallow trenching for wires, and mark the sensor locations somehow so I don't mow over them.

But by the age of nine, a noticeable gap begins to emerge — girls’ confidence and enthusiasm for STEM subjects often start to ...

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 ...

When I started working on my soil moisture sensor, I had little idea about how harsh an environment the soil really is. In this , cool failure modes & solutions when sticking electronics in the ...

Soil moisture is measured 3-6cm around the sensor, so they can monitor larger volumes of soil and, when installed correctly, offer more representative results than other types of sensors.

University of Wisconsin–Madison engineers have developed low-cost sensors that allow for real-time, continuous monitoring of nitrate in soil types that are common in Wisconsin. These printed ...

For now, just moisture. However, there's no reason I can't add more sensors if I want to. pH isn't something that's going to be changing rapidly. I can check that annually and probably be fine.
