Abstract: Internet of things (IoT) systems for precision agriculture offer the opportunity for more efficient use of water and fertilizers. Here, capacitive moisture sensors are screen-printed on a ...

This paper addresses the optimization and implementation of a fringing field capacitive soil moisture sensor using the printed circuit board technology. It includes the analysis of a novel ...

A new study has uncovered a surprising and concerning paradox: although Earth's vegetation cover has expanded dramatically over the past four decades, this widespread "greening" trend is often ...

The NASA Soil Moisture Active Passive (SMAP) mission, launched in 2015, has over 10 years of global L-band radiometry observations. The low frequency [1.4 GHz frequency or 21 cm (8 in) wavelength ...
