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 ...

As such, I'd like to build myself some wireless moisture sensors for moderate scale production (consider 50 test points reasonable).

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 ...

Soil moisture sensors are cheap and easy to interface with, to the point that combining one with an Arduino and blinking an LED when your potted plant is feeling a bit parched is a common beginners… ...
