The soil moisture sensor module , built around the LM393 comparator, gives an active-low (L) level output when the soil is dry (determined by a pre-setted threshold value). This digital output (wet ...

This system enables fast and spatially resolved detection of the molecular composition of soil. It uses Shifted Excitation Raman Difference Spectroscopy (SERDS), which is based on a dual ...

Cheng’s team designed and fabricated a high-performance sensor to completely decouple the detection of nitrogen loss and soil temperature. The multi-parameter sensor is based on vanadium oxide ...

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 ...

These novel optical nanosensors developed by SMART DiSTAP exhibit changes in their fluorescence intensity upon the detection of arsenic. Embedded in plant tissues with no detrimental effects on the ...

After having landed, they're subsequently imaged by a drone – perhaps the same one that deployed them – which is equipped with a fLiDAR (fluorescence Light Detection and Ranging) system.

Researchers from the University of Glasgow have developed compostable, screen-printed soil sensors made from biodegradable materials that break down into plant nutrients. These sensors could ...

Researchers have developed a new optical sensor that provides a simple way to achieve real-time detection of extremely low levels of arsenic in water.
