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 ...

So a low-power radio network for soil moisture sensors is certainly a welcome development. We can think of a lot of ways that sensors could be powered in the field.

A frequent beginner project involves measuring soil moisture levels by measuring its resistance with a couple of electrodes. These electrodes are available ready-made as PCBs, but suffer badly from… ...

ONTARIO, Ore. — As Oregon State University researcher Udayakumar Sekaran sees it, soil-moisture sensors help farmers irrigate more efficiently but are limited by the wires to which they are ...
