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 ...

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. ... (wires, pcb) in the dry soil and measure the ...

My shed is mostly done, which means I'm moving onto other projects that look a lot like landscaping. Lawns, gardens, etc. I want to be efficient in my watering, and potentially even lazy and have ...

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 … ...

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 ...

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.

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. An experimental new sensor could be particularly helpful, as it incorporates a ...
