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 ...

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 ...

Probes were constructed to measure non-destructively the moisture content of soil in a pot. The thermal conductivity of the soil was determined using a line-source of heat which yielded measurements ...

A new satellite from NASA, scheduled to launch on 29 January, may help to improve those predictions. The Soil Mapping Active Passive (SMAP) probe uses microwave measurements to plot moisture levels in ...
