Leaf Wetness Smart Sensor

$180.00 USD
Provides accurate leaf wetness data in a number of growing and research applications; ready to use, requires no painting or coating.


Provides accurate leaf wetness data in a number of growing and research applications. This sensor, which is ready to use and does not require any painting or coating, uses a capacitive grid that is less sensitive to surface residues than resistive grid-based sensors, and comes preconditioned for consistent measurements between sensors and for long-term stability. Along with a 3-meter cable, a mounting bracket is included so the sensor can be easily positioned to mimic the wet-dry characteristics of the plants being studied.
