Leaf wetness sensor

The leaf wetness sensor can determine the degree of leaf wetness, the duration of a certain state (wet or dry) and detects whether there are precipitations or condensation. Depending on the degree of humidity, the sensor detects a change in electrical resistance on the elements of the grid and the output signal can be acquired by a data logger (standard output 0÷2 Vdc, or normalized 4÷20 mA or digital RS485/Modbus).
