The soil moisture sensor module , built around the LM393 comparator, gives an active-low (L) level output when the soil is dry (determined by a pre-setted threshold value). This digital output (wet ...

In a way, the magic of a soil moisture sensor’s functionality boils down to a simple RC circuit. But of course, in practice there is a bit more to it than that. [rbaron] explains exactly how … ...

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. ... Where electronics engineers discover the latest ...

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.

Soil sensors are handy things, but while sensing moisture is what they do, how they handle that data is what makes them useful.Ensuring usefulness is what led [Maakbaas] to design and create an ...

We report the design and installation of a distributed soil moisture sensor network in a riparian zone within the Whitewater Basin in Central Kansas. The soil-moisture monitoring network used in this ...

Soil moisture sensors can help farmers save water, by letting them know when their crops actually need to be watered. A new sensor could be particularly helpful, as it incorporates a special ...
