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 ...

This is a simple arduino project for a soil moisture sensor that will light up a LED at a certain moisture level. It uses Arduino Duemilanove microcontroller board. Two wires placed in the soil pot ...

For my totally-hypothetical at this point wireless soil moisture sensor project, I've been thinking about using supercapacitors.

Although we generally think of Internet of Things (IoT) and similar devices as things that are scattered around above ground, there are plenty of reasons to also have such devices underground. These ...

Plant-related posts are growing in popularity on Gadget Master, when regularly watered with attention... so hopefully this Arduino-based system to monitor soil conditions will be of interest. It's the ...
