But of course, in practice there is a bit more to it than that. [rbaron] explains exactly how capacitive soil moisture sensors work simply, clearly, and concisely.

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 ...

Soil-moisture solutions company Sensoterra is ramping up its LoRaWAN-based technology sales by partnering with Internet of Things (IoT) company Kerlink. By using the Kerlink reference design in its ...

The sensor will turn off the system for that day. The sensor isn’t foolproof, though. First, the sensors work best in spring and fall when we usually get the most rain.
