Maturity stage TRL 6 / 7 - Prototype demonstration 1:1

The presence of water on leaves can indicate a risk of fungal disease, making accurate, real-time leaf wetness measurement essential. AgriHawk, a patented humectation sensor stands out for its lower cost and higher resolution. Unlike traditional sensors, it monitors an entire area by scanning detection, providing data every minute. Using a laser and a camera, the measurement of wetness is based on the Heiligenschein phenomenon, which occurs on hydrophobic surfaces, reflecting a large amount of light back to the receiver. On hydrophilic surfaces, on the other hand, the appearance of water reduces the amount of light reflected. This difference in light behavior is exploited to accurately assess the moisture content of leaves.
