The hardware is consists of an Arduino microcontroller (here an Arduino Uno R3) and a pre-wired soil moisture sensor module. The soil moisture sensor module , built around the LM393 comparator, gives ...

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 ...

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 ...

My soil-moisture reading was in the low 700s in soil that had around 30 percent moisture (according to a comparison with a commercial soil-moisture sensor), and 661 in a drier pot.
