If you are designing your own intelligent “Graden Computer” with an optional digital plant moisture sensor/water pump controller that lights an LED to alert the user when it is time to water a potted ...

Soil moisture measurement is fundamental to understanding hydrological processes, crop water dynamics, and broader environmental monitoring. Recent advancements have driven the development of ...

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 ...

Neutrons propelled to Earth by cosmic rays from space are helping scientists in more than 25 countries to measure water in soil and help farmers save water and adapt to climate change. With a cosmic ...

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 material ...

Electricity can be a pretty handy tool when it stays within the bounds of its wiring. It’s largely responsible for our modern world and its applications are endless. When it’s not running in wires or ...

Measuring soil moisture with time-domain reflectometry (TDR) sensors can aid in turfgrass water conservation efforts and help improve playing conditions. However, information is lacking on the ...

Researchers from North Carolina State University have developed a wireless system that uses radio transmitters and receivers to estimate soil moisture in agricultural fields at multiple depths in real ...
