Soil moisture is the most important hydrologic state variable that directly impacts the global environment and human society. In recognition of its significance, soil moisture has been included in the list of the most fundamental climate variables by the Global Climate Observing System initiative that is co-sponsored by the World Meteorological Organization. A recent article in Reviews of Geophysics explores the latest advances in measurement and monitoring of soil moisture from the pedon to the global scales and discusses opportunities for future research. Here, the authors of the paper answer some questions about basic concepts and methodological developments in this field.

Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
